The level of intellectual engagement with Chomsky's ideas in the comments here is shockingly low. Surely, we are capable of holding these two thoughts: one, that the facility of LLMs is fantastic and useful, and two, that the major breakthroughs of AI this decade have not, at least so far, substantially deepened our understanding of our own intelligence and its constitution.
That may change, particularly if the intelligence of LLMs proves to be analogous to our own in some deep way—a point that is still very much undecided. However, if the similarities are there, so is the potential for knowledge. We have a complete mechanical understanding of LLMs and can pry apart their structure, which we cannot yet do with the brain. And some of the smartest people in the world are engaged in making LLMs smaller and more efficient; it seems possible that the push for miniaturization will rediscover some tricks also discovered by the blind watchmaker. But these things are not a given.

> AI this decade have not, at least so far, substantially deepened our understanding of our own intelligence and its constitution
I would push back on this a little bit. While it has not helped us to understand our own intelligence, it has made me question whether such a thing even exists. Perhaps there are no simple and beautiful natural laws, like those that exists in Physics, that can explain how humans think and make decisions. When CNNs learned to recognize faces through a series of hierarchical abstractions that make intuitive sense it's hard to deny the similarities to what we're doing as humans. Perhaps it's all just emergent properties of some messy evolved substrate.
The big lesson from the AI development in the last 10 years from me has been "I guess humans really aren't so special after all" which is similar to what we've been through with Physics. Theories often made the mistake of giving human observers some kind of special importance, which was later discovered to be the cause of theories not generalizing.

I didn't see where he was disagreeing with this.
I'm assuming this was the part you were saying he doesn't hold, because it is pretty clear he holds the second thought.
| is it likely that programs will be devised that surpass human capabilities? We have to be careful about the word “capabilities,” for reasons to which I’ll return. But if we take the term to refer to human performance, then the answer is: definitely yes.
I have a difficult time reading this as saying that LLMs aren't fantastic and useful.
| We can make a rough distinction between pure engineering and science. There is no sharp boundary, but it’s a useful first approximation. Pure engineering seeks to produce a product that may be of some use. Science seeks understanding.
This seems to be the core of his conversation. That he's talking about the side of science, not engineering.

There was an interesting debate where Chomsky took a position on intelligence being rooted in symbolic reasoning and Asimov asserted a statistical foundation (ah, that was not intentional ;).
LLM designs to date are purely statistical models. A pile, a morass of floating point numbers and their weighted relationships, along with the software and hardware that animates them and the user input and output that makes them valuable to us. An index of the data fed into them, different from a Lucene or SQL DB index made from compsci algorithms & data structure primitives. Recognizable to Azimov's definition.
And these LLMs feature no symbolic reasoning whatsoever within their computational substrate. What they do feature is a simple recursive model: Given the input so far, what is the next token? And they are thus enabled after training on huge amounts of input material. No inherent reasoning capabilities, no primordial ability to apply logic, or even infer basic axioms of logic, reasoning, thought. And therefore unrecognizable to Chomsky's definition.
So our LLMs are a mere parlor trick. A one-trick pony. But the trick they do is oh-so vastly complicated, and very appealing to us, of practical application and real value. It harkens back to the question: What is the nature of intelligence? And how to define it?
And I say this while thinking of the marked contrast of apparent intelligence between an LLM and say a 2-year age child.
sdwr · 55m ago
That's not true, symbols emerge out of the statistics. Just look at the imagenet analysis that identified distinct concepts in different layers, or the experiments with ablation in LLMs.
They may not be doing strict formal logic, but they are definitely compressing information into, and operating using, symbols.

The fact that we have figured out how to translate language into something a computer can "understand" should thrill linguists. Taking a word (token) and abstracting it's "meaning" as a 1,000-dimension vector seems like something that should revolutionize the field of linguistics. A whole new tool for analyzing and understanding the underlying patterns of all language!
And there's a fact here that's very hard to dispute, this method works. I can give a computer instructions and it "understands" them in a way that wasn't possible before LLMs. The main debate now is over the semantics of words like "understanding" and whether or not an LLM is conscious in the same way as a human being (it isn't).
krackers · 5h ago
Restricted to linguistics, LLM's supposed lack of understanding should be a non-sequitur. If the question is whether LLMs have formed a coherent ability to parse human languages, the answer is obviously yes. In fact not just human languages, as seen with multimodality the same transformer architecture seems to work well to model and generate anything with inherent structure.
I'm surprised that he doesn't mention "universal grammar" once in that essay. Maybe it so happens that humans do have some innate "universal grammar" wired in by instinct but it's clearly not _necessary_ to be able to parse things. You don't need to set up some explicit language rules or generative structure, enough data and the model learns to produce it. I wonder if anyone has gone back and tried to see if you can extract out some explicit generative rules from the learned representation though.
Since the "universal grammar" hypothesis isn't really falsifiable, at best you can hope for some generalized equivalent that's isomorphic to the platonic representation hypothesis and claim that all human language is aligned in some given latent representation, and that our brains have been optimized to be able to work in this subspace. That's at least a testable assumption, by trying to reverse engineer the geometry of the space LLMs have learned.

Can LLMs actually parse human languages? Or can they react to stimuli with a trained behavioral response? Dogs can learn to sit when you say "sit", and learn to roll over when you say "roll over". But the dog doesn't parse human language; it reacts to stimuli with a trained behavioral response.
(I'm not that familiar with LLM/ML, but it seems like trained behavioral response rather than intelligent parsing. I believe this is part of why it hallucinates? It doesn't understand concepts, it just spits out words - perhaps a parrot is a better metaphor?)
Xss3 · 3h ago
Dogs out of all creatures probably actually do have some parsing going on for human language. They learn it like we do, picking up context from the environment, actions, tone, facial expressions, body language, etc.
You can say 'what's that' in many different ways and a clever dog will react differently for each, even if it's the first time it's heard you say 'what's that?' In a scared tone it'll still react differently while knowing what you're asking.
They even do the cute head tilt when they're struggling to understand something.
I think people vastly underestimate the power of wetware and think animals and us are separated by a chasm, but I think it's a relatively small leap.
We base so much of our understanding of other creatures intelligence on their ability to communicate with us or express things in the ways we do. If elephants judged humans on their ability to communicate in infrasound to speak their names (yes they have names for each other) they'd wouldn't think too highly of us.
Sidenote but the latest I've heard is that elephants like us because they think we are cute.

The analogy I've used before is a bright first-grader named Johnny. Johnny stumbles across a high school algebra book. Unless Johnny's last name is von Neumann, he isn't going to get anything out of that book. An LLM will.

I think people give training data too much credit. Obviously it's important, but it also isn't a database of knowledge like it's made out to be.
You can see this in riddles that are obviously in the training set, but older or lighter models still get them wrong. Or situations where the model gets them right, but uses a different method than the ones used in the training set.

An LLM will get ... what exactly ? The ability to reorder its sentences ? The LLM doesn't think, doesn't understand, doesn't know what matters more than not, doesn't use what it learns, doesn't expand what it learns to new knowledge, doesn't enjoy reading that book and doesn't suffer through it.
So what is it really gonna do with a book, that LLM ? Reorder its internal matrix to be a little bit more precise when autocompleting sentences sounding like the book ? We could build an nvidia cluster the size of the Sun and it would repeat sentences back to us in unbelievable ways but would still be unable to take a knowledge-based decision, I fear.
So what are we in awe at exactly ? A pretty parrot.
The day the Chinese room metaphor disappears is when ChatGPT replies to you that your question is so boring it doesn't want to expend the resources to think about it.

This isn't really the meaning of the Chinese room. The Chinese room presupposes that the output is identical to that of a speaker who understands the language.

They are really not neuronal analogs, reasoning is far from what they do. If they reasoned, they'd stick to their guns more readily, but try to contradict an LLM and it will make any logic leap you ask it too.
If you debate with me, I'll keep reasoning on the same premises and usually the difference between two humans is not in reasoning but in choice of premises.
For instance you really want here to assert that LLM are close to human, I want to assert they're not - truth is probably in between but we chose two camps. We'll then reason from these premises, reach antagonistic conclusions and slowly try to attack each other point.
An LLM cannot do that, it cannot attack your point very well, it doesn't know how to say you're wrong, because it doesn't care anyway. It just completes your sentences, so if you say "now you're wrong, change your mind" it will, which sounds far from reasoning to me, and quite unreasonable in fact.

LLMs are modelling the world, not just "predicting the next token". They are certainly not akin to parrots. Some examples here[1][2][3]. Anyone claiming otherwise at this point is not arguing in good faith.
Maybe it takes some world modeling to do it as well as they do, but ultimately they are just predicting the next token. These things are not mutually exclusive.

It can have a sensible conversation with you, follow your instructions, do math and physics, and write code that performs the task you described in English. Some models can create pictures and videos matching the description you gave them, or write descriptions of a video from you.
In 2023, Microsoft released a paper saying GPT4 could do things like tell you how to stack a random collection of unrelated variously-shaped objects so they don't fall over. Things have come a long way since then.
Try out one of the advanced models, and see whether you think it understands concepts.
krackers · 3h ago
You can train LLMs on the output very complex CFGs, and it successfully learns the grammar and hierarchy needed to complete any novel prefix. This is a task much more recursive and difficult than human languages, so there's no reason to believe that LLMs aren't able to parse human languages in the formal sense as well.
And of course empirically LLMs do generate valid English sentences. They may not necessarily be _correct_ sentences in a propositional truth-value sense (as seen by so-called "hallucinations), but they are semantically "well-formed" in contrast to Chomsky's famous example of the failure of probabilistic grammar models, "Colorless green ideas sleep furiously."
I'm not a linguist but I don't think linguistics has ever cared about the truth value of a sentence, that's more under the realm of logic.

I’ve seen ChatGPT generate bad English and I’ve seen the layer or logic / UI re-render the page as I think there is a simple spell checker that kicks in and tells the api to re-render and recheck.
I don’t believe for one second that LLMs reason, understand, know, anything.
There are plenty of times LLMs fail to generate correct sentences, and plenty of times they fail to generate correct words.
Around the time ChatGPT rolled out web search inside actions, you’d get really funky stuff back and watch other code clearly try to catch the run away.
o3 can be hot garbage if you ask it expand a specific point inside a 3 paragraph memo, the reasoning models perform very, very poorly when they are not summarizing.
There are times where the thing works like magic, other times, asking it to write me a PowerShell script that gets users by first and last name has it inventing commands that flags that don’t exist.
If the model ‘understood’, ‘followed, some sort of structure outside parroting stuff it already knows about it would be easy to spot and guide it via prompts. That is not the case even with the most advanced models today.
It’s clear that LLMs work best at specific small tasks that have a well established pattern defined in a strict language or api.
I’ve broken o3 trying to have it lift working python code, into formal python code, how? The person that wrote the code didn’t exactly code it how a developer would code a program. 140 lines of basic grab some data generate a table broke the AI and it had the ‘informal’ solution in the prompt. So no there is zero chance LMMs do more than predict.

I disagree, I think it's clear in the article that Chomsky thinks a language also should have a human purpose.
The compression we use in languages to not label impossible adjectives against impossible nouns (green ideas is impossible as ideas don't have colors, we could have a suffix on every noun to mark what can be colored and what cannot) is because we need to transfer these over the air, and quickly, before the lion jumps on the hunter. It's one of the many attributes of "languages in the wild" (Chinese doesn't use "tenses" really, can you imagine the compressive value?), and that's what Chomsky says here:
Proceeding further with normal science, we find that the internal processes and elements of the language cannot be detected by inspection of observed phenomena. Often these elements do not even appear in speech (or writing), though their effects, often subtle, can be detected. That is yet another reason why restriction to observed phenomena, as in LLM approaches, sharply limits understanding of the internal processes that are the core objects of inquiry into the nature of language, its acquisition and use. But that is not relevant if concern for science and understanding have been abandoned in favor of other goals.
Understand what he means: you can read a million text through a machine, it will never infer why we don't label adjective and nouns to prevent confusion and "green ideas". But for us it's painfully obvious, we don't have time when we speak to do all that. And I come from a language when we label every noun with a gender, I can see how stupid and painful it is to grasp for foreigners: it doesn't make any sense. Why do we do it ? Ask ChatGPT, will it tell you that it's because we like how beautiful it all sounds, which is the stupid reason why we do that ?

Language and intelligence are mostly orthogonal to each other and development of linguistic skills appeared very late in human evolutionary terms.

Animals definitely parse human language, some to a significant extent.
Like an airplane taking off, things that seem like “emergent behavior” and hard lines of human vs animal behavior are really matters of degree that, like the airplane, we don’t notice until it actually takes flight… then we think there is a clean line between flying and not flying, but there isn’t. The airplane is gradually becoming weightless until it breaks contact with the ground, and animals use and understand language, but we only notice when it seems human.

I'm not sure if it's even up for debate that they parse human language, in fact they do it better than most people do. Parsing is just breaking up language into it's component ideas and fitting those ideas to one another to achieve meaning. We can meaningfully argue whether they are capable of novel reasoning (probably not) or whether they can apply knowledge from one domain to another (sometimes!) but parsing seems undeniable.

The terms are too unclear here. Can you define what it means to "be able to parse human language"? I'm sure contemporary chatbots score higher on typical reading comprehension tests than most humans.

>is something implicitly present in both our minds and an LLM
The LLM doesn't start with any real structure besides the network of ops though. If there is any induced structure, it's learnable from the data. And given enough data the base network is sufficient to learn the "grammar" of not just human language but more complex CFGs and things you wouldn't traditionally consider "languages" as well (e.g. audio, images). In a sort of chicken/egg scenario, the morasses of data gives rise to the structures needed to parse and generate that data.

> The fact that we have figured out how to translate language into something a computer can "understand" should thrill linguists.
I think they are really excited by this. There seems no deficiency of linguists using these machines.
But I think it is important to distinguish the ability to understand language and translate it. Enough that you yourself put quotes around "understanding". This can often be a challenge for many translators, not knowing how to properly translate something because of underlying context.
Our communication runs far deeper than the words we speak or write on a page. This is much of what linguistics is about, this depth. (Or at least that's what they've told me, since I'm not a linguist) This seems to be the distinction Chomsky is trying to make.
> The main debate now is over the semantics of words like "understanding" and whether or not an LLM is conscious in the same way as a human being (it isn't).
Exactly. Here, I'm on the side of Chomsky and I don't think there's much of a debate to be had. We have a long history of being able to make accurate predictions while erroneously understanding the underlying causal nature.
My background is physics, and I moved into CS (degrees in both), working on ML. I see my peers at the top like Hinton[0] and Sutskever[1] making absurd claims. I call them absurd, because it is a mistake we've made over and over in the field of physics[2,3]. One of those lessons you learn again and again, because it is so easy to make the mistake. Hinton and Sutskever say that this is a feature, not a bug. Yet we know it is not enough to fit the data. Fitting the data allows you to make accurate, testable predictions. But it is not enough to model the underlying causal structure. Science has a long history demonstrating accurate predictions with incorrect models. Not just in the way of the Relativity of Wrong[4], but more directly. Did we forget that the Geocentric Model could still be used to make good predictions? Copernicus did not just face resistance from religious authorities, but also academics. The same is true for Galileo, Boltzmann, Einstein and many more. People didn't reject their claims because they were unreasonable. They rejected the claims because there were good reasons to. Just... not enough to make them right.
> whether or not an LLM is conscious in the same way as a human being
The problem is... that there is a whole amount of "smart" activities humans do without being conscious of it.
- Walking, riding a bike, or typing on a keyboard happen fluidly without conscious planning of each muscle movement.
- You can finish someone sentence or detect if a sentence is grammatically wrong, often without being able to explain the rule.
- When you enter a room, your brain rapidly identifies faces, furniture, and objects without you consciously thinking, “That is a table,” or “That is John.”

"The fact that we have figured out how to translate language into something a computer can "understand" should thrill linguists."
No, there is no understanding at all. Please don't confuse codifying with understanding or translation. LLMs don't understand their input, they simply act on it based on the way they are trained on it.
"And there's a fact here that's very hard to dispute, this method works. I can give a computer instructions and it "understands" them "
No, it really does not understand those instructions. It is at best what used to be called an "idiot savant". Mind you, people used to describe others like that - who is the idiot?
Ask your favoured LLM to write a programme in a less used language - ooh let's try VMware's PowerCLI (it's PowerShell so quite popular) and get it to do something useful. It wont because it can't but it will still spit out something. PowerCLI is not extant across Stackoverflow and co much but it is PS based so the LLMs will hallucinate madder than a hippie on a new super weed.

Maybe I am missing context, but it seems like he’s defending himself from the claim that we shouldn’t bother studying language acquisition and comprehension in humans because of LLM’s?
Who would make such a claim? LLM’s are of course incredible, but it seems obvious that their mechanism is quite different than the human brain.
I think the best you can say is that one could motivate lines of inquiry in human understanding, especially because we can essentially do brain surgery on an LLM in action in a way that we can’t with humans.
It's amusing that he argues (correctly) that "there is no Great Chain of Being with humans at the top," but then claims that LLMs cannot tell us anything about language because they can learn "impossible languages" that infants cannot learn. Isn't that an anthropomorphic argument, saying that what a language is inherently defined by human cognition?

I confess my opinion of Noam Chomsky dropped a lot from reading this interview. The way he set up a "Tom Jones" strawman and kept dismissing positions using language like "we'd laugh", "total absurdity", etc. was really disappointing. I always assumed that academics were only like that on reddit, and in real life they actually made a serious effort at rigorous argument, avoiding logical fallacies and the like. Yet here is Chomsky addressing a lay audience that has no linguistics background, and instead of even attempting to summarize the arguments for his position, he simply asserts that opposing views are risible with little supporting argument.

He justifies the statement in the previous sentence (which you don't quote) where he says that it is self-evident by virtue of the fact that something exists at the beginning (i.e. it's not empty space). That's the "merest truism". No popsci article is going to help understand that if you don't already.

That's understandable but irrelevant. Only a few people have major interest in how humans think exactly. But nearly everyone is hang on the question if the LLMs could think better.

It's not irrelevant, it's the core of the disconnect: The problem is that everyone is arguing as if they passionately care about how humans work when, as you say, they don't care at all.
People should just recognize, as you have done, that they don't actually care about how the human language faculty works. It's baffling that they instead choose to make absurd arguments to defend fields they don't care one way or another about.
When Chomsky says that LLMs aren't how the human faculty works it would be so easy to tell the truth and say "I don't care how the human language faculty works" and everyone can go focus on the things they are interested in, just as it would be easy for a GPS designer to say "I don't care how insect navigation works".
There is no problem as long as you don't pretend to be caring about (this aspect of) science.

Lol. It's clear you are not interested in having any kind of rational discussion on the topic and are driven by some kind of zealotry when you claim to have read a technical 40 page paper (with an additional 18 pages of citations) in 30 minutes.

It’s certainly not a dense paper with careful nuanced derivations that you have to ponder to grasp. It’s a light read you can skim especially if you aren’t interested in LLM Trump improv and you are familiar with the general thought behind connectionism, construction grammar, other modern linguistic theories and, of course, universal grammar. The debate is as old as UG, but now with a new LLM flavor.
I don’t know which argument you expect from me. I read it and found nothing similar to “Stop wasting your time; naval vessels do it all the time.” So I concluded it’s a strawman. Being against a particular controversial approach in linguistics doesn’t mean being against science.
foobarqux · 5h ago
> I read it and found nothing similar to “Stop wasting your time; naval vessels do it all the time.”
You implied in the previous paragraph that you didn't in fact read it and you only "skimmed" it. Maybe that's why you "found nothing similar to 'stop wasting your time; naval vessels do it all the time". But even in skimming the paper it's incomprehensible how you could miss it: At least the first 23 pages of the draft version I have just describe how well LLMs perform and completely ignores the relevant question of how human language works. (It doesn't get any better after the first 23 pages). So presumably you just don't know what an analogy is and are literally searching for the term "naval vessels".
Here's just one example demonstrating that Piantodosi does in fact claim what Chomsky says he does: Piantodosi writes "The success of large language models is a failure for generative theories because
it goes against virtually all of the principles these theories have espoused." Rewriting that statement using Chomsky's analogy illustrates how idiotic the original statement is: "The success of naval vessels is a failure for insect navigation theories because it goes against all of the principles these theories have espoused".
LudwigNagasena · 4h ago
There is a difference between supporting one research paradigm over another and rejecting science altogether to focus on engineering. The first quote and the context around it implies the latter.
The success of naval vessels shows it’s possible to navigate without innate star and wind comprehension, so maybe we should think of that inner stuff as phlogiston. (Yeah, this analogy isn’t as nice but it’s quite hard to translate the nuance of linguistic debate into nautical terms.)

All this interview proves is that Chomsky has fallen far, far behind how AI systems work today and is retreating to scoff at all the progress machine learning has achieved. Machine learning has given rise to AI now. It can't explain itself from principles or its architecture. But you couldn't explain your brain from principles or its architecture, you'd need all of neuroscience to do it. Because the brain is digital and (probably) does not reason like our brains do, it somehow falls short?
While there's some things in this I find myself nodding along to in this, I can't help but feel it's an a really old take that is super vague and hand-wavy. The truth is that all of the progress on machine learning is absolutely science. We understand extremely well how to make neural networks learn efficiently; it's why the data leads anywhere at all. Backpropagation and gradient descent are extraordinarily powerful. Not to mention all the "just engineering" of making chips crunch incredible amounts of numbers.
Chomsky is extremely ungenerous to the progress and also pretty flippant about what this stuff can do.

> Not to mention all the "just engineering" of making chips crunch incredible amounts of numbers.
Are LLM's still the same black box as they were described as a couple years ago? Are their inner workings at least slightly better understood than in the past?
Running tens of thousands of chips crunching a bajillion numbers a second sounds fun, but that's not automatically "engineering". You can have the same chips crunching numbers with the same intensity just to run an algorithm to run a large prime number. Chips crunching numbers isn't automatically engineering IMO. More like a side effect of engineering? Or a tool you use to run the thing you built?
What happens when we build something that works, but we don't actually know how? We learn about it through trial and error, rather than foundational logic about the technology.
Sorta reminds me of the human brain, psychology, and how some people think psychology isn't science. The brain is a black box kind of like a LLM? Some people will think it's still science, others will have less respect.
This perspective might be off base. It's under the assumption that we all agree LLM's are a poorly understood black box and no one really knows how they truly work. I could be completely wrong on that, would love for someone else to weigh in.
Separately, I don't know the author, but agreed it reads more like a pop sci book. Although I only hope to write as coherently as that when I'm 96 y/o.

Not if some properties are unexpectedly emergent. Then it is science. For instance, why should a generic statistical model be able to learn how to fill in blanks in text using a finite number of samples? And why should a generic blank-filler be able to produce a coherent chat bot that can even help you write code?
Some have even claimed that statistical modelling shouldn't able to produce coherent speech, because it would need impossible amounts of data, or the optimisation problem might be too hard, or because of Goedel's incompleteness theorem somehow implying that human-level intelligence is uncomputable, etc. The fact that we have a talking robot means that those people were wrong. That should count as a scientific breakthrough.

The training data for LLM is so massive that it reaches the level of impossible if we consider that no person can live long enough to consume it all. Or even a small percent of it.
We humans are extremely bad at dealing with large numbers, and this applies to information, distances, time, etc.

But not much if you're interested in finding out how our brain works, or how language works. One of the interesting outcomes of LLMs is that there apparently is a way to represent complex ideas and their linguistic connection in a (rather large) unstructured state, but it comes without thorough explanation or relation to the human brain.

Should we? This reminds me acutely of imaginary numbers. They are a great theory of numbers that can list many numbers that do 'exist' and many that can't possibly 'exist'. And we did laugh when imaginary numbers were first introduced - the name itself was intended as a derogatory term for the concept. But who's laughing now?
chongli · 10h ago
Imaginary numbers are not relevant at all. There’s nothing whatsoever to do with the everyday use of the word imaginary. They could just as easily have been called “vertical numbers” and real numbers called “horizontal numbers” in order to more clearly illustrate their geometric interpretation in the complex plane.
The term “imaginary number” was coined by Rene Descartes as a derogatory and the ill intent behind his term has stuck ever since. I suspect his purpose was theological rather than mathematical and we are all the worse for it.

If we had some kind of system that can put together proper working DNA for all the creatures that ever actually existed on this planet, some half of them would be completely nonviable if introduced to the ecosystem today. He is failing to see that there is an incredible understanding of systems that we are producing with this work, but he is a very old man from a very different time and contrarianism is often the only way to look smart or reasoned when you have no clue whats actually going on, so I am not shocked by his take.

klabb3 · 2h ago
> Maybe LLMs do teach us something about language... that language is complicated.
It certainly teaches us many things. But an LLM trained on as many words (or generally speaking an AI trained on sounds) in similar quantities of a toddler learning to understand, parse and apply language, would not perform well with current architectures. They need orders of magnitude more training material to get even close. Basically, current AI learns slowly, but of course it’s much faster in wall clock time because it’s all computer.
What I mean is: what makes an ALU (CPU) better than a human at arithmetic? It’s just faster and makes fewer errors. Similarly, what makes Google or Wikipedia better than an educated person? It’s just storing and helping you access stored information, it’s not magic (anymore). You can manually do everything mechanically, if you’re willing to waste the time to prove a point.
An LLM does many things better than humans, but we forget they’ve been trained on all written history and have hundreds of billions of parameters. If you compare what an LLM can do with the same amount of training to a human, the human is much better even at picking up patterns – current AIs strongest skill. The magic comes from the unseen vast amounts of training data. This is obvious when using them – stray just slightly outside of the training zone to unfamiliar domains and ”ability” drops rapidly. The hard part is figuring out these fuzzy boundaries. How far does interpolating training data get you? What are the highest level patterns are encoded in the training data? And most importantly, to what extent do those patterns apply to novel domains?
Alternatively, you can use LLMs as a proxy for understanding the relationship between domains, instead of letting humans label them and decide the taxonomy. One such example is the relationship between detecting patterns and generating text and images – it turns out to be more or less reversible through the same architecture. More such remarkable similarities and anti-similarities are certainly on the horizon. For instance, my gut feeling says that small talk is closer to driving a car but very different from puzzle solving. We don’t really have a (good) taxonomy over human- or animal brain processes.
skydhash · 10h ago
Quite a nice overview. For almost any specific measure, you can find something that is better than human at that point. And now LLMs architecture have made possible for computers to produce complete and internally consistent paragraphs of text, by rehashing all the digital data that can be found on the internet.
But what we're good as using all of our capabilities to transform the world around us according to an internal model that is partially shared between individuals. And we have complete control over that internal model, diverging from reality and converging towards it on whims.
So we can't produce and manipulate text faster, but rarely the end game is to produce and manipulate text. Mostly it's about sharing ideas and facts (aka internal models) and the control is ultimately what matters. It can help us, just like a calculator can help us solve an equation.
EDIT
After learning to draw, I have that internal model that I switch to whenever I want to sketch something. It's like a special mode of observation, where you no longer simply see, but pickup a lot of extra details according to all the drawing rules you internalized. There's not a lot, they're just intrinsically connected with each other. The difficult part is hand-eye coordination and analyzing the divergences between what you see and the internal model.
I think that's why a lot of artists are disgusted with AI generators. There's no internal models. Trying to extract one from a generated picture is a futile exercice. Same with generated texts. Alterations from the common understanding follows no patterns.
randmeerkat · 10h ago

A calculator is consistent and doesn’t “hallucinate” answers to equations. An LLM puts an untrustworthy filter between the truth and the person. Google was revolutionary because it increased access to information. LLMs only obscure that access, while pretending to be something more.

I'm not a native english speaker, so I've used for an essay where they told us to target a certain word count. I was close, but the verbiage to get to that word count doesn't come naturally to me. So I used Germini and tell it to rewrite the text targeting that word count (my only prompt). Then I reviewed the answer, rewriting where it strayed from the points I was making.
Also I used it for a few programming tasks I was pretty sure was in the datasets (how to draw charts with python and manipulate pandas frame). I know the domain, but wasn't in the mood to analyse the docs to get the implementation information. But the information I was seeking was just a few lines of sample code. In my experience, anything longer is pretty inconsistent and worthless explanations.

Chomsky's problem here has nothing to do with his politics, but unfortunately a lot to do with his long-held position in the Nature/Nurture debate - a position that is undermined by the ability of LLMs to learn language without hardcoded grammatical rules:
Chomsky introduced his theory of language acquisition, according to which children have an inborn quality of being biologically encoded with a universal grammar
Leftists and intellectuals overlap a lot. LLM text must be still full of six fingered hands to many of them.
For Chomsky specifically, the entire existence of LLM, however it's framed, is a massive middle finger to him and a strike-through on a large part of his academic career. As much as I find his UG theory and its supporters irritating, it might be felt a bit unfair to someone his age.

It is unfortunate opinion, because I personally hold Chomsky in fairly high regard and give most of his thoughts I am familiar with a reasonable amount of consideration if only because he could, I suppose in the olden days now, articulate his points well and make you question your own thought process. This no longer seems to be the case though as I found the linked article somewhat difficult to follow. I suppose age can get to anyone.
Not that I am an LLM zealot. Frankly, some of the clear trajectory it puts humans on makes me question our futures in this timeline. But even if I am not a zealot, but merely an amused, but bored middle class rube, the serious issues with it ( privacy, detailed personal profiling that surpasses existing systems, energy use, and actual power of those who wield it ), I can see it being implemented everywhere with a mix of glee and annoyance.
I know for a fact it will break things and break things hard and it will be people, who know how things actually work that will need to fix those.
I will be very honest though. I think Chomsky is stuck in his internal model of the world and unable to shake it off. Even his arguments fall flat, because they don't fit the domain well. It seems like they should given that he practically made his name on syntax theory ( which suggests his thoughts should translate well into it ) and yet.. they don't.
I have a minor pet theory on this, but I am still working on putting it into some coherent words.
godelski · 1h ago
I think many people are missing the core of what Chomsky is saying. It is often easy to miscommunicate and I think this is primarily what is happening. I think the analogy he gives here really helps emphasize what he's trying to say.
If you're only going to read one part, I think it is this:
| I mentioned insect navigation, which is an astonishing achievement. Insect scientists have made much progress in studying how it is achieved, though the neurophysiology, a very difficult matter, remains elusive, along with evolution of the systems. The same is true of the amazing feats of birds and sea turtles that travel thousands of miles and unerringly return to the place of origin.
| Suppose Tom Jones, a proponent of engineering AI, comes along and says: “Your work has all been refuted. The problem is solved. Commercial airline pilots achieve the same or even better results all the time.”
| If even bothering to respond, we’d laugh.
| Take the case of the seafaring exploits of Polynesians, still alive among Indigenous tribes, using stars, wind, currents to land their canoes at a designated spot hundreds of miles away. This too has been the topic of much research to find out how they do it. Tom Jones has the answer: “Stop wasting your time; naval vessels do it all the time.”
| Same response.
It is easy to look at metrics of performance and call things solved. But there's much more depth to these problems than our abilities to solve some task. It's not about just the ability to do something, the how matters. It isn't important that we are able to do better at navigating than birds or insects. Our achievements say nothing about what they do.
This would be like saying we developed a good algorithm only my looking at it's ability to do some task. Certainly that is an important part, and even a core reason for why we program in the first place! But its performance tells us little to nothing about its implementation. The implementation still matters! Are we making good uses of our resources? Certainly we want to be efficient, in an effort to drive down costs. Are there flaws or errors that we didn't catch in our measurements? Those things come at huge costs and fundamentally limit our programs in the first place. The task performance tells us nothing about the vulnerability to hackers nor what their exploits will cost our business.
That's what he's talking about.
Just because you can do something well doesn't mean you have a good understanding. It's natural to think the two relate because understanding improves performance that that's primarily how we drive our education. But this is not a necessary condition and we have a long history demonstrating that. I'm quite surprised this concept is so contentious among programmers. We've seen the follies of using test driven development. Fundamentally, that is the same. There's more depth than what we can measure here and we should not be quick to presume that good performance is the same as understanding[0,1]. We KNOW this isn't true[2].
I agree with Chomsky, it is laughable. It is laughable to think that the man in The Chinese Room[3] must understand Chinese. 40 years in, on a conversation hundreds of years old. Surely we know you can get a good grade on a test without actually knowing the material. Hell, there's a trivial case of just having the answer sheet.
Chomsky’s notion is: LLMs can only imitate, not understand language. But what exactly is understanding? What if our „understanding“ is just unlocking another level in a model? Unlocking a new form of generation?

> But what exactly is understanding?
He alludes to quite a bit here - impossible languages, intrinsic rules that don’t actually express in the language, etc - that leads me to believe there’s a pretty specific sense by which he means “understanding,” and I’d expect there’s a decent literature in linguistics covering what he’s referring to. If it’s a topic of interest to you, chasing down some of those leads might be a good start.
(I’ll note as several others have here too that most of his language seems to be using specific linguistics terms of art - “language” for “human language” is a big tell, as is the focus on understanding the mechanisms of language and how humans understand and generate languages - I’m not sure the critique here is specifically around LLMs, but more around their ability to teach us things about how humans understand language.)

I have trouble with the notion "understanding". I get the usefulness of the word, but I don't think that we are capable to actually understand. I also think that we are not even able to test for understanding - a good imitation is as good as understanding. Also, understanding has limits. In school, they often say on class that you should forget whatever you have been taught so far, because this new layer of knowledge that they are about to teach you. Was the previous knowledge not "understanding" then? Is the new one "understanding"?
If we define "understanding" like "useful", as in, not an innate attribute, but something in relation to a goal, then again, a good imitation, or a rudimentary model can get very far. ChatGPT "understood" a lot of things I have thrown at it, be that algorithms, nutrition, basic calculations, transformation between text formats, where I'm stuck in my personal development journey, or how to politely address people in the email I'm about to write.

From some Googling and use of Claude (and from summaries of the suggestively titled "Impossible Languages" by Moro linked from https://en.wikipedia.org/wiki/Universal_grammar ), it looks like he's referring to languages which violate the laws which constrain the languages humans are innately capable of learning. But it's very unclear why "machine M is capable of learning more complex languages than humans" implies anything about the linguistic competence or the intelligence of machine M.

Firstly, can't speak for Chomsky.
In this article he is very focused on science and works hard to delineate science (research? deriving new facts?) from engineering (clearly product oriented). In his opinion ChatGPT falls on the engineering side of this line: it's a product of engineering, OpenAI is concentrating on marketing. For sure there was much science involved but the thing we have access to is a product.
IMHO Chomsky is asking: while ChatGPT is a fascinating product, what is it teaching us about language? How is it advancing our knowledge of language? I think Chomsky is saying "not much."
Someone else mentioned embeddings and the relationship between words that they reveal. Indeed, this could be a worthy area of further research. You'd think it would be a real boon when comparing languages. Unfortunately the interviewer didn't ask Chomsky about this.

This is where I'm stuck.
For other commentators, as I understand it, Chomsky's talking about well-defined grammar and language and production systems. Think Hofstadter's Godel Escher Bach. Not "folk" understanding of language.
I have no understanding or intuition, or even a finger nail grasp, for how an LLM generates, seemingly emulating, "sentences", as though created with a generative grammar.
Is any one comparing and contrasting these two different techniques? Being noob, I wouldn't even know where to start looking.
I've gleaned that someone(s) are using LLM/GPT to emit abstract syntax trees (vs a mere stream of tokens), to serve as input for formal grammars (eg programming source code). That sounds awesome. And something I might some day sorta understand.
I've also gleaned that, given sufficient computing power, training data for future LLMs will have tokenized words (vs just character sequences). Which would bring the two strategies closer...? I have no idea.
(Am noob, so forgive my poor use of terminology. And poor understanding of the tech, too.)

I don't really understand your question but if a deep neural network predicts the weather we don't have any problem accepting that the deep neural network is not an explanatory model of the weather (the weather is not a neural net). The same is true of predicting language tokens.
fc417fc802 · 4h ago
> is not an explanatory model of the weather (the weather is not a neural net)
I don't follow. Aren't those entirely separate things? The most accurate models of anything necessarily account for the underlying mechanisms. Perhaps I don't understand what you mean by "explanatory"?
Specifically in the case of deep neural networks, we would generally suppose that it had learned to model the underlying reality. In effect it is learning the rules of a sufficiently accurate simulation.
foobarqux · 4h ago
> The most accurate models of anything necessarily account for the underlying mechanisms
But they don't necessarily convey understanding to humans. Prediction is not explanation.
There is a difference between Einstein's General Theory of Relativity and a deep neural network that predicts gravity. The latter is virtually useless for understanding gravity (that's even if makes better predictions).
> Specifically in the case of deep neural networks, we would generally suppose that it had learned to model the underlying reality. In effect it is learning the rules of a sufficiently accurate simulation.
No, they just fit surface statistics, not underlying reality. Many physics phenomena were predicted using theories before they were observed, they would not be in the training data even though they were part of the underlying reality.
fc417fc802 · 4h ago
> No, they just fit surface statistics, not underlying reality.
I would dispute this claim. I would argue that as models become more accurate they necessarily more closely resemble the underlying phenomena which they seek to model. In other words, I would claim that as a model more closely matches those "surface statistics" it necessarily more closely resembles the underlying mechanisms that gave rise to them. I will admit that's just my intuition though - I don't have any means of rigorously proving such a claim.
I have yet to see an example where a more accurate model was conceptually simpler than the simplest known model at some lower level of accuracy. From an information theoretic angle I think it's similar to compression (something that ML also happens to be almost unbelievably good at). Related to this, I've seen it argued somewhere (I don't immediately recall where though) that learning (in both the ML and human sense) amounts to constructing a world model via compression and that rings true to me.
> Many physics phenomena were predicted using theories before they were observed
Sure, but what leads to those theories? They are invariably the result of attempting to more accurately model the things which we can observe. During the process of refining our existing models we predict new things that we've never seen and those predictions are then used to test the validity of the newly proposed models.
foobarqux · 3h ago
This is getting away from the original point which is that deep neural networks are, by default, not explanatory in the way Einstein's theory of relativity is.
But even so,
> In other words, I would claim that as a model more closely matches those "surface statistics" it necessarily more closely resembles the underlying mechanisms that gave rise to them.
I don't what it means, for example, for a deep neural network, to "more resemble" the underlying process of the weather. It's also obviously false in general: If you have a mechanical clock and quartz-crystal analog clock you are not going to be able to derive the internal workings of either or distinguish between them from the hand positions. The same is true for two different pseudo-random number generator circuits that produce the same output.
> I have yet to see an example where a more accurate model was conceptually simpler than the simplest known model at some lower level of accuracy.
I don't understand what you mean. Simple models often yield a high level of understanding without being better predictors. For example an idealized ball rolling down a plane, Galileo's mass/gravity thought experiment, Kepler etc. Many of these models ignore less important details to focus on the fundamental ones.
> From an information theoretic angle I think it's similar to compression (something that ML also happens to be almost unbelievably good at).

In practice you get nowhere trying to recreate the internals of a cryptographic pseudo-random number generator from the output it produces (maybe in theory you could do it with infinite data and no bounds on computational complexity or something) even though the generator itself could be highly compressed.
> Sure, but what leads to those theories? They are invariably the result of attempting to more accurately model the things which we can observe.
Yes but if the model does not lead to understanding you cannot come up with the new ideas.
fc417fc802 · 1h ago
Admittedly my original question (how "not explanatory" leads to "is not a") begins to look like a nit now that I understand the point you were trying to make (or at least I think I do). Nonetheless the discussion seems interesting.
That said, I'm inclined to object to this "explanatory" characteristic you're putting forward. We as humans certainly put a lot of work into optimizing the formulation of our models with the express goal of easing human understanding but I'm not sure that's anything more than an artifact of the system that produces them. At the end of the day they are tools for accomplishing some purpose.
Perhaps the idea you are attempting to express is analogous to concepts such as principal component analysis as applied to the representation of the final model?
> If you have a mechanical clock and quartz-crystal analog clock you are not going to be able to derive the internal workings of either or distinguish between them from the hand positions.
Arguably modern physics analogously does exactly that, although the amount of resources required to do so is astronomical.
Anyhow my claim was not about the ability or lack thereof to derive information from the outputs of a system. It was that as you demand increased accuracy from a model of the hand positions (your example) you will be necessarily forced to model the internal workings of the original physical system to increasingly higher fidelity. I claim that there is no way around this - that fundamentally your only option for increasing the accuracy of the output of a model is for it to more closely resemble the inner workings of the thing being modeled. Taken to the (notably impossible) extreme this might take the form of a quantum mechanics based simulation of the entire system.
Extrapolating this to the weather, I'm claiming that any reasonably accurate ML model will necessarily encompass some sort of underlying truth about the physical system that it is modeling and that as it becomes more accurate it will encode more such truth. Notably, I make no claim about the ability of an unaided human to interpret such truths from a binary blob of weights.
> I don't understand what you mean. Simple models often yield a high level of understanding without being better predictors.
I said nothing about efficiency of educating humans (ie information gathering by or transfer between agents) but rather about model accuracy versus model complexity. I am claiming that more accurate models will invariably be more complex, and that said complexity will invariably encode more information about the original system being modeled. I have yet to encounter a counterexample.
> [CSPRNG recreation]
It is by design impossible to "model" the output of such a function in a bitwise accurate manner without reproducing the internals with perfect fidelity. In the event that someone figures out how to model the output in an imprecise manner without access to the key that would generally be construed as the algorithm having been broken. In other words that example aligns perfectly with my point in the sense that it cannot be approximated to any degree better than random chance with a "simpler" (ie less computationally complex than the original) mechanism. It takes the continuum of accuracy that I was originally describing and replaces it with a step function.
> Yes but if the model does not lead to understanding you cannot come up with the new ideas.
I suppose human understanding is a prerequisite to new human constructed models but my (counter-)point remains. Physics theories are "nothing more" than humans fitting "surface statistics" to increasing degrees of accuracy. I think this is a fairly fundamental truth with regards to the philosophy of science.

Chomsky is always saying that LLMs and such can only imitate, not understand language. But I wonder if there is a degree of sophistication at which he would concede these machines exceed "imitation". If his point is that LLMs arrive at language in a way different than humans... great. But I'm not sure how he can argue that some kind of extremely sophisticated understanding of natural language is not embedded in these models in a way that, at this point, exceeds the average human. In all fairness, this was written in 2023, but given his longstanding stubbornness on this topic, I doubt it would make a difference.
mattnewton · 10h ago
I think what would "convince" Chomsky is more akin to the explainability research currently in it's infancy, producing something akin to a branch of information theory for language and thought.
Chomsky talks about how the current approach can't tell you about what humans are doing, only approximate it; the example he has given in the past is taking thousands of hours of footage of falling leaves and then training a model to make new leaf falling footage versus producing a model of gravity, gas mechanics for the air currents, and air resistance model of leaves. The later representation is distilled down into something that tells you about what is happening at the end of some scientific inquiry, and the former is a opaque simulation for engineering purposes if all you wanted was more leaf falling footage.
So I interpret Chomsky as meaning "Look, these things can be great for an engineering purpose but I am unsatisfied in them for scientific research because they do not explain language to me" and mostly pushing back against people implying that the field he dedicated much of his life to is obsolete because it isn't being used for engineering new systems anymore, which was never his goal.
flornt · 10h ago
I guess it's because LLM does not understand the meaning as you understand what you read or thought. LLMs are machines that modulate hierarchical positions, ordering the placement of a-signifying sign without a clue of the meaning of what they ordered (that's why machine can hallucinate :they don't have a sense of what they express)

Even if you constructed some system the output of which could not be distinguished from human-produced language but that either (1) clearly operated according to principles other than those that govern human language or (2) operated according to principles that its creators could not adequately explain, it would not be of that much interest to him.
He wants to understand how human language works. If I get him right — and I'm absolutely sure that I don't in important ways — then LLMs are not that interesting because both (1) and (2) above are true of them.

"Expert in (now-)ancient arts draws strange conclusion using questionable logic" is the most generous description I can muster.
Quoting Chomsky:
> These considerations bring up a minor problem with the current LLM enthusiasm: its total absurdity, as in the hypothetical cases where we recognize it at once. But there are much more serious problems than absurdity.
> One is that the LLM systems are designed in such a way that they cannot tell us anything about language, learning, or other aspects of cognition, a matter of principle, irremediable... The reason is elementary: The systems work just as well with impossible languages that infants cannot acquire as with those they acquire quickly and virtually reflexively.
Response from o3:
LLMs do surface real linguistic structure:
• Hidden syntax: Attention heads in GPT-style models line up with dependency trees and phrase boundaries—even though no parser labels were ever provided. Researchers have used these heads to recover grammars for dozens of languages.
• Typology signals: In multilingual models, languages that share word-order or morphology cluster together in embedding space, letting linguists spot family relationships and outliers automatically.
• Limits shown by contrast tests: When you feed them “impossible” languages (e.g., mirror-order or random-agreement versions of English), perplexity explodes and structure heads disappear—evidence that the models do encode natural-language constraints.
• Psycholinguistic fit: The probability spikes LLMs assign to next-words predict human reading-time slow-downs (garden-paths, agreement attraction, etc.) almost as well as classic hand-built models.
These empirical hooks are already informing syntax, acquisition, and typology research—hardly “nothing to say about language.”
foobarqux · 9h ago
> LLMs do surface real linguistic structure...
It's completely irrelevant because the point he's making is that LLMs operate differently from human languages as evidenced by the fact that they can learn language structures that humans cannot learn. Put another way, I'm sure you can point out an infinitude of similarities between human language faculty and LLMs but it's the critical differences that make LLMs not useful models of human language ability.
> When you feed them “impossible” languages (e.g., mirror-order or random-agreement versions of English), perplexity explodes and structure heads disappear—evidence that the models do encode natural-language constraints.
This is confused. You can pre-train an LLM on English or an impossible language and they do equally well. On the other hand humans can't do that, ergo LLMs aren't useful models of human language because they lack this critical distinctive feature.
Yes it's true, you can read my response to one of the authors @canjobear describing the problem with that paper in the comment linked below. But to summarize: in order to show what they want to show they have to take the simple, interesting languages based on linear order that Moro showed a human cannot learn and show that LLMs also can't learn them and they don't do that.
The reason the Moro languages are of interest are that they are computationally simple so it's a puzzle why humans can't learn them (and no surprise that LLMs can). The authors of the paper miss the point and show irrelevant things like there exist complicated languages that both humans and LLMs can't learn.
> You can pre-train an LLM on English or an impossible language and they do equally well
It's impressive that LLMs can learn languages that humans cannot. In what frame is this a negative?
Separately, "impossible language" is a pretty clear misnomer. If an LLM can learn it, it's possible.
foobarqux · 8h ago
The latter. Moro showed that you can construct simple language rules, in particular linear rules, like the third word of every sentence modifies the noun, that humans have a hard time learning (specifically they use different parts of their brain in MRI scans and take longer to process than control languages) and are different from conventional human language structure (which hierarchical structure dependent, i.e. roughly that words are interpreted according to their position in a parse tree not their linear order).
That's what "impossible language" means in this context, not something like computationally impossible or random.

Well, yes. And "reasoning" is only something LLMs do coincidentally, to their function as sequence continuation engines. Like performing accurate math on rationale numbers, it can happen if you put in a lot of work and accept a LOT of expensive computation. Even then there exists computations that just are not reasonable or feasible.

dghlsakjg · 7h ago
My point is that computers, when used properly, can absolutely do math. And LLMs, when used properly, can absolutely explain the reasoning behind why a pound of bricks and a pound of feathers weigh the same.
Can they reason? Maybe, depending on your definition of reasoning.
An example: which weighs more a pound of bricks and 453.59 grams of feathers? Explain your reasoning.
LLM: The pound of bricks weighs slightly more.
*Reasoning:*
* *1 pound* is officially defined as *0.45359237 kilograms*, which is *453.59237 grams*.
* You have *453.59 grams* of feathers.
So, the pound of bricks (453.59237 grams) weighs a tiny fraction more than the 453.59 grams of feathers. For most practical purposes, they'd be considered the same, but technically, the bricks are heavier by 0.00237 grams. /llm
It is both correct and the reasoning is sound. Do I understand that the machine is a pattern following machine, yes! Is there an argument to be made that humans are also that? Probably. Chomsky himself argued in favor of a universal grammar, after all.
I’m steel manning this a bit, but the point is that LLMs are capable of doing some things which are indistinguishable from human reasoning in terms of results. Does the process matter in all cases?

Generally what people are talking about are his universal grammar or generative syntax theories/approaches, which are foundational to how you approach many topics.

This leads to people who agree hiring each other and departments ‘circling the wagon’ on these issues. You’ll see this referred to as east vs west coast, but it’s not actually that clearly geographically delineated.

I don't have a degree in linguistics, but I took a few classes about 15 years ago, and Chomsky's works were basically treated as gospel. Although my university's linguistics faculty included several of his former graduate students, so maybe there's a bias factor. In any case, it reminds me of an SMBC comic about how math and science advance over time [1]
Linguistics has been largely subsumed by CS (LLM, speech synthesis, translation). It's not an empirical science or social science and most of its theories are not falsifiable.
But generally speaking Chomsky's ideas, and in particular, the Universal Grammar are no longer in vogue.
Calavar · 11m ago
Linguistics is a heterogenous field, an while some parts aren't empirical, others absolutely are. I can attest to that from the journal articles I read in undergrad. They had experimental data and statistical analyses.
That may change, particularly if the intelligence of LLMs proves to be analogous to our own in some deep way—a point that is still very much undecided. However, if the similarities are there, so is the potential for knowledge. We have a complete mechanical understanding of LLMs and can pry apart their structure, which we cannot yet do with the brain. And some of the smartest people in the world are engaged in making LLMs smaller and more efficient; it seems possible that the push for miniaturization will rediscover some tricks also discovered by the blind watchmaker. But these things are not a given.
I would push back on this a little bit. While it has not helped us to understand our own intelligence, it has made me question whether such a thing even exists. Perhaps there are no simple and beautiful natural laws, like those that exists in Physics, that can explain how humans think and make decisions. When CNNs learned to recognize faces through a series of hierarchical abstractions that make intuitive sense it's hard to deny the similarities to what we're doing as humans. Perhaps it's all just emergent properties of some messy evolved substrate.
The big lesson from the AI development in the last 10 years from me has been "I guess humans really aren't so special after all" which is similar to what we've been through with Physics. Theories often made the mistake of giving human observers some kind of special importance, which was later discovered to be the cause of theories not generalizing.
I'm assuming this was the part you were saying he doesn't hold, because it is pretty clear he holds the second thought.
I have a difficult time reading this as saying that LLMs aren't fantastic and useful. This seems to be the core of his conversation. That he's talking about the side of science, not engineering.LLM designs to date are purely statistical models. A pile, a morass of floating point numbers and their weighted relationships, along with the software and hardware that animates them and the user input and output that makes them valuable to us. An index of the data fed into them, different from a Lucene or SQL DB index made from compsci algorithms & data structure primitives. Recognizable to Azimov's definition.
And these LLMs feature no symbolic reasoning whatsoever within their computational substrate. What they do feature is a simple recursive model: Given the input so far, what is the next token? And they are thus enabled after training on huge amounts of input material. No inherent reasoning capabilities, no primordial ability to apply logic, or even infer basic axioms of logic, reasoning, thought. And therefore unrecognizable to Chomsky's definition.
So our LLMs are a mere parlor trick. A one-trick pony. But the trick they do is oh-so vastly complicated, and very appealing to us, of practical application and real value. It harkens back to the question: What is the nature of intelligence? And how to define it?
And I say this while thinking of the marked contrast of apparent intelligence between an LLM and say a 2-year age child.
They may not be doing strict formal logic, but they are definitely compressing information into, and operating using, symbols.
And there's a fact here that's very hard to dispute, this method works. I can give a computer instructions and it "understands" them in a way that wasn't possible before LLMs. The main debate now is over the semantics of words like "understanding" and whether or not an LLM is conscious in the same way as a human being (it isn't).
I'm surprised that he doesn't mention "universal grammar" once in that essay. Maybe it so happens that humans do have some innate "universal grammar" wired in by instinct but it's clearly not _necessary_ to be able to parse things. You don't need to set up some explicit language rules or generative structure, enough data and the model learns to produce it. I wonder if anyone has gone back and tried to see if you can extract out some explicit generative rules from the learned representation though.
Since the "universal grammar" hypothesis isn't really falsifiable, at best you can hope for some generalized equivalent that's isomorphic to the platonic representation hypothesis and claim that all human language is aligned in some given latent representation, and that our brains have been optimized to be able to work in this subspace. That's at least a testable assumption, by trying to reverse engineer the geometry of the space LLMs have learned.
(I'm not that familiar with LLM/ML, but it seems like trained behavioral response rather than intelligent parsing. I believe this is part of why it hallucinates? It doesn't understand concepts, it just spits out words - perhaps a parrot is a better metaphor?)
You can say 'what's that' in many different ways and a clever dog will react differently for each, even if it's the first time it's heard you say 'what's that?' In a scared tone it'll still react differently while knowing what you're asking.
They even do the cute head tilt when they're struggling to understand something.
I think people vastly underestimate the power of wetware and think animals and us are separated by a chasm, but I think it's a relatively small leap.
We base so much of our understanding of other creatures intelligence on their ability to communicate with us or express things in the ways we do. If elephants judged humans on their ability to communicate in infrasound to speak their names (yes they have names for each other) they'd wouldn't think too highly of us.
Sidenote but the latest I've heard is that elephants like us because they think we are cute.
IMHO, no, they have nothing approaching understanding. It's Chinese Rooms[1] all the way down, just with lots of bell and whistles. Spicy autocomplete.
1. https://en.wikipedia.org/wiki/Chinese_room
The analogy I've used before is a bright first-grader named Johnny. Johnny stumbles across a high school algebra book. Unless Johnny's last name is von Neumann, he isn't going to get anything out of that book. An LLM will.
So much for the Chinese Room.
That analogy only holds if LLMs can solve novel problems that can be proven to not exist in any form in their training material.
You can see this in riddles that are obviously in the training set, but older or lighter models still get them wrong. Or situations where the model gets them right, but uses a different method than the ones used in the training set.
It may appear that they are solving novel problems but given the size of their training set they have probably seen them. There are very few questions a person can come up with that haven't already been asked and answered somewhere.
Granted, for most language and programming tasks, you don’t need the latter, only the former.
It's famously easier to impress people with soft-sciences speculation than it is to impress the rules of math or compilers.
Similarly, they've ingested human-centuries or more of spelling bee related text, but can't reliably count the number of Rs in strawberry. (yes, I understand tokenization is to blame for a large part of this. perhaps that kind of limitation applies to other things too?)
So what is it really gonna do with a book, that LLM ? Reorder its internal matrix to be a little bit more precise when autocompleting sentences sounding like the book ? We could build an nvidia cluster the size of the Sun and it would repeat sentences back to us in unbelievable ways but would still be unable to take a knowledge-based decision, I fear.
So what are we in awe at exactly ? A pretty parrot.
The day the Chinese room metaphor disappears is when ChatGPT replies to you that your question is so boring it doesn't want to expend the resources to think about it. But it'd be ready to talk about this or that, that it's currently trying to get better at. When it finally has agency over its own intelligence. When it acquires a purpose.
- of course they reason
The claim of the “stochastic parrot” needs to go away
Eg see: https://www.anthropic.com/news/golden-gate-claude
I think the rub is that people think you need consciousness to do reasoning, I’m NOT claiming LLMs have consciousness or awareness
If you debate with me, I'll keep reasoning on the same premises and usually the difference between two humans is not in reasoning but in choice of premises.
For instance you really want here to assert that LLM are close to human, I want to assert they're not - truth is probably in between but we chose two camps. We'll then reason from these premises, reach antagonistic conclusions and slowly try to attack each other point.
An LLM cannot do that, it cannot attack your point very well, it doesn't know how to say you're wrong, because it doesn't care anyway. It just completes your sentences, so if you say "now you're wrong, change your mind" it will, which sounds far from reasoning to me, and quite unreasonable in fact.
Because languages have many similar concepts so the operator inside the Chinese room can understand nearly all the concepts without speaking Chinese.
And the LLM can translate to and from any language trivially, the inner layers do the actual understanding of concepts.

In 2023, Microsoft released a paper saying GPT4 could do things like tell you how to stack a random collection of unrelated variously-shaped objects so they don't fall over. Things have come a long way since then.
Try out one of the advanced models, and see whether you think it understands concepts.
And of course empirically LLMs do generate valid English sentences. They may not necessarily be _correct_ sentences in a propositional truth-value sense (as seen by so-called "hallucinations), but they are semantically "well-formed" in contrast to Chomsky's famous example of the failure of probabilistic grammar models, "Colorless green ideas sleep furiously."
I'm not a linguist but I don't think linguistics has ever cared about the truth value of a sentence, that's more under the realm of logic.
I don’t believe for one second that LLMs reason, understand, know, anything.
There are plenty of times LLMs fail to generate correct sentences, and plenty of times they fail to generate correct words.
Around the time ChatGPT rolled out web search inside actions, you’d get really funky stuff back and watch other code clearly try to catch the run away.
o3 can be hot garbage if you ask it expand a specific point inside a 3 paragraph memo, the reasoning models perform very, very poorly when they are not summarizing.
There are times where the thing works like magic, other times, asking it to write me a PowerShell script that gets users by first and last name has it inventing commands that flags that don’t exist.
If the model ‘understood’, ‘followed, some sort of structure outside parroting stuff it already knows about it would be easy to spot and guide it via prompts. That is not the case even with the most advanced models today.
It’s clear that LLMs work best at specific small tasks that have a well established pattern defined in a strict language or api.
I’ve broken o3 trying to have it lift working python code, into formal python code, how? The person that wrote the code didn’t exactly code it how a developer would code a program. 140 lines of basic grab some data generate a table broke the AI and it had the ‘informal’ solution in the prompt. So no there is zero chance LMMs do more than predict.
And to be clear, it one shot a whole thing for me last night, using the GitHub/Codex/agent thing in VS code, probably saved me 30 minutes but god forbid you start from a bad / edge / poorly structured thing that doesn’t fit the mould.
The compression we use in languages to not label impossible adjectives against impossible nouns (green ideas is impossible as ideas don't have colors, we could have a suffix on every noun to mark what can be colored and what cannot) is because we need to transfer these over the air, and quickly, before the lion jumps on the hunter. It's one of the many attributes of "languages in the wild" (Chinese doesn't use "tenses" really, can you imagine the compressive value?), and that's what Chomsky says here:
Proceeding further with normal science, we find that the internal processes and elements of the language cannot be detected by inspection of observed phenomena. Often these elements do not even appear in speech (or writing), though their effects, often subtle, can be detected. That is yet another reason why restriction to observed phenomena, as in LLM approaches, sharply limits understanding of the internal processes that are the core objects of inquiry into the nature of language, its acquisition and use. But that is not relevant if concern for science and understanding have been abandoned in favor of other goals.
Understand what he means: you can read a million text through a machine, it will never infer why we don't label adjective and nouns to prevent confusion and "green ideas". But for us it's painfully obvious, we don't have time when we speak to do all that. And I come from a language when we label every noun with a gender, I can see how stupid and painful it is to grasp for foreigners: it doesn't make any sense. Why do we do it ? Ask ChatGPT, will it tell you that it's because we like how beautiful it all sounds, which is the stupid reason why we do that ?
Babies and in particular Deaf babies understand and communicate significant amount of information w/o parsing sentences. Dogs don't parse human speech, they associate an emotion to the particular sound and body language exhibited to them, repeatedly.
Like an airplane taking off, things that seem like “emergent behavior” and hard lines of human vs animal behavior are really matters of degree that, like the airplane, we don’t notice until it actually takes flight… then we think there is a clean line between flying and not flying, but there isn’t. The airplane is gradually becoming weightless until it breaks contact with the ground, and animals use and understand language, but we only notice when it seems human.
I'm not sure there's much evidence for this one way or another at this point.
The LLM doesn't start with any real structure besides the network of ops though. If there is any induced structure, it's learnable from the data. And given enough data the base network is sufficient to learn the "grammar" of not just human language but more complex CFGs and things you wouldn't traditionally consider "languages" as well (e.g. audio, images). In a sort of chicken/egg scenario, the morasses of data gives rise to the structures needed to parse and generate that data.
I'm not actually comfortable saying that LLMs aren't conscious. I think there's a decent chance they could be in a very alien way.
I realize that this is a very weird and potentially scary claim for people to parse but you must understand how weird and scary consciousness is.
But I think it is important to distinguish the ability to understand language and translate it. Enough that you yourself put quotes around "understanding". This can often be a challenge for many translators, not knowing how to properly translate something because of underlying context.
Our communication runs far deeper than the words we speak or write on a page. This is much of what linguistics is about, this depth. (Or at least that's what they've told me, since I'm not a linguist) This seems to be the distinction Chomsky is trying to make.
Exactly. Here, I'm on the side of Chomsky and I don't think there's much of a debate to be had. We have a long history of being able to make accurate predictions while erroneously understanding the underlying causal nature.My background is physics, and I moved into CS (degrees in both), working on ML. I see my peers at the top like Hinton[0] and Sutskever[1] making absurd claims. I call them absurd, because it is a mistake we've made over and over in the field of physics[2,3]. One of those lessons you learn again and again, because it is so easy to make the mistake. Hinton and Sutskever say that this is a feature, not a bug. Yet we know it is not enough to fit the data. Fitting the data allows you to make accurate, testable predictions. But it is not enough to model the underlying causal structure. Science has a long history demonstrating accurate predictions with incorrect models. Not just in the way of the Relativity of Wrong[4], but more directly. Did we forget that the Geocentric Model could still be used to make good predictions? Copernicus did not just face resistance from religious authorities, but also academics. The same is true for Galileo, Boltzmann, Einstein and many more. People didn't reject their claims because they were unreasonable. They rejected the claims because there were good reasons to. Just... not enough to make them right.

The problem is... that there is a whole amount of "smart" activities humans do without being conscious of it.
- Walking, riding a bike, or typing on a keyboard happen fluidly without conscious planning of each muscle movement.
- You can finish someone sentence or detect if a sentence is grammatically wrong, often without being able to explain the rule.
- When you enter a room, your brain rapidly identifies faces, furniture, and objects without you consciously thinking, “That is a table,” or “That is John.”
No, there is no understanding at all. Please don't confuse codifying with understanding or translation. LLMs don't understand their input, they simply act on it based on the way they are trained on it.
"And there's a fact here that's very hard to dispute, this method works. I can give a computer instructions and it "understands" them "
No, it really does not understand those instructions. It is at best what used to be called an "idiot savant". Mind you, people used to describe others like that - who is the idiot?
Ask your favoured LLM to write a programme in a less used language - ooh let's try VMware's PowerCLI (it's PowerShell so quite popular) and get it to do something useful. It wont because it can't but it will still spit out something. PowerCLI is not extant across Stackoverflow and co much but it is PS based so the LLMs will hallucinate madder than a hippie on a new super weed.
Who would make such a claim? LLM’s are of course incredible, but it seems obvious that their mechanism is quite different than the human brain.
I think the best you can say is that one could motivate lines of inquiry in human understanding, especially because we can essentially do brain surgery on an LLM in action in a way that we can’t with humans.
That part is unusually good btw.
I happen to agree with his view, so i came armed to agree and read this with a view in mind which I felt was reinforced. People are overstating the AGI qualities and misapplying the tool, sometimes the same people.
In particular, the lack of theory, and scientific method means both we're, not learning much, and we've rei-ified the machine.
I was disappointed nothing said of Norbert Weiner. A man who invented cybernetics and had the courage to stand up to the military industrial complex.
"The first principle is that you must not fool yourself, and you are the easiest person to fool."
The same way that reddit comments arent a formal debate.
Mocking is absolutely useful. Sometimes you debate someone like graham hancock and force him to confirm that he has no evidence for his hypotheses, then when you discuss the debate, you mock him relentlessly for having no evidence for his hypotheses.
> Yet here is Chomsky addressing a lay audience that has no linguistics background
So not a formal debate or paper where I would expect anyone to hold to debate principles.
> instead of even attempting to summarize the arguments for his position..
He makes a very clear, simple argument, accessible to any layperson who can read. If you are studying insects what you are interested in is how insects do it not what other mechanisms you can come up with to "beat" insects. This isn't complicated.
Where is the research on impossible language that infants can't acquire? A good popsci article would give me leads here.
Even assuming Chomsky's claim is true, all it shows is that LLMs aren't an exact match for human language learning. But even an inexact model can still be a useful research tool.
>That’s highly unlikely for reasons long understood, but it’s not relevant to our concerns here, so we can put it aside. Plainly there is a biological endowment for the human faculty of language. The merest truism.
Again, a good popsci article would actually support these claims instead of simply asserting them and implying that anyone who disagrees is a simpleton.
I agree with Chomsky that the postmodern critique of science sucks, and I agree that AI is a threat to the human race.
It's not infants, it's adults but Moro "Secrets of Words" is a book that describes the experiments and is aimed at lay people.
> Even assuming Chomsky's claim is true, all it shows is that LLMs aren't an exact match for human language learning. But even an inexact model can still be a useful research tool.
If it is it needs to be shown, not assumed. Just as you wouldn't by default assume that GPS navigation tells you about insect navigation (though it might somehow).
> Again, a good popsci article would actually support these claims instead of simply asserting them and implying that anyone who disagrees is a simpleton.
He justifies the statement in the previous sentence (which you don't quote) where he says that it is self-evident by virtue of the fact that something exists at the beginning (i.e. it's not empty space). That's the "merest truism". No popsci article is going to help understand that if you don't already.
People should just recognize, as you have done, that they don't actually care about how the human language faculty works. It's baffling that they instead choose to make absurd arguments to defend fields they don't care one way or another about.
When Chomsky says that LLMs aren't how the human faculty works it would be so easy to tell the truth and say "I don't care how the human language faculty works" and everyone can go focus on the things they are interested in, just as it would be easy for a GPS designer to say "I don't care how insect navigation works".
There is no problem as long as you don't pretend to be caring about (this aspect of) science.
I searched for an actual paper by that guy because you’ve mentioned his real name. I found “Modern language models refute Chomsky’s approach to language”. After reading it seems even more true that Chomsky’s Tom Jones is a strawman.
Lol. It's clear you are not interested in having any kind of rational discussion on the topic and are driven by some kind of zealotry when you claim to have read a technical 40 page paper (with an additional 18 pages of citations) in 30 minutes.
Even if by some miraculous feat you had read it you haven't made a single actual argument or addressed any of the points made by Chomsky.
I don’t know which argument you expect from me. I read it and found nothing similar to “Stop wasting your time; naval vessels do it all the time.” So I concluded it’s a strawman. Being against a particular controversial approach in linguistics doesn’t mean being against science.
You implied in the previous paragraph that you didn't in fact read it and you only "skimmed" it. Maybe that's why you "found nothing similar to 'stop wasting your time; naval vessels do it all the time". But even in skimming the paper it's incomprehensible how you could miss it: At least the first 23 pages of the draft version I have just describe how well LLMs perform and completely ignores the relevant question of how human language works. (It doesn't get any better after the first 23 pages). So presumably you just don't know what an analogy is and are literally searching for the term "naval vessels".
Here's just one example demonstrating that Piantodosi does in fact claim what Chomsky says he does: Piantodosi writes "The success of large language models is a failure for generative theories because it goes against virtually all of the principles these theories have espoused." Rewriting that statement using Chomsky's analogy illustrates how idiotic the original statement is: "The success of naval vessels is a failure for insect navigation theories because it goes against all of the principles these theories have espoused".
The success of naval vessels shows it’s possible to navigate without innate star and wind comprehension, so maybe we should think of that inner stuff as phlogiston. (Yeah, this analogy isn’t as nice but it’s quite hard to translate the nuance of linguistic debate into nautical terms.)
This quote brought to mind the very different technological development path of the spider species in Adrian Tchaikovsky's Children of Time. They used pheromones to 'program' a race of ants to do computation.
Sounds like "ineffable nature" mumbo-jumbo.
Tempus fugit.
What is elegant as a model is not always what works, and working towards a clean model to explain everything from a model that works is fraught, hard work.
I don’t think anyone alive will realize true “AGI”, but it won’t matter. You don’t need it, the same way particle physics doesn’t need elegance
I agree with the rest of these comments though, listening to Chomsky wax about the topic-du-jour is a bit like trying to take lecture notes from the Swedish Chef.
I'll be liberally borrowing, and using that simile! It's hilarious. Bork, bork, bork!
The best thing is you can be right, and the other side can't take offense. It's the Muppets after all. It's brilliant!
While there's some things in this I find myself nodding along to in this, I can't help but feel it's an a really old take that is super vague and hand-wavy. The truth is that all of the progress on machine learning is absolutely science. We understand extremely well how to make neural networks learn efficiently; it's why the data leads anywhere at all. Backpropagation and gradient descent are extraordinarily powerful. Not to mention all the "just engineering" of making chips crunch incredible amounts of numbers.
Chomsky is extremely ungenerous to the progress and also pretty flippant about what this stuff can do.
I think we should probably stop listening to Chomsky; he hasn't said anything here that he hasn't already say a thousand times for decades.
Are LLM's still the same black box as they were described as a couple years ago? Are their inner workings at least slightly better understood than in the past?
Running tens of thousands of chips crunching a bajillion numbers a second sounds fun, but that's not automatically "engineering". You can have the same chips crunching numbers with the same intensity just to run an algorithm to run a large prime number. Chips crunching numbers isn't automatically engineering IMO. More like a side effect of engineering? Or a tool you use to run the thing you built?
What happens when we build something that works, but we don't actually know how? We learn about it through trial and error, rather than foundational logic about the technology.
Sorta reminds me of the human brain, psychology, and how some people think psychology isn't science. The brain is a black box kind of like a LLM? Some people will think it's still science, others will have less respect.
This perspective might be off base. It's under the assumption that we all agree LLM's are a poorly understood black box and no one really knows how they truly work. I could be completely wrong on that, would love for someone else to weigh in.
Separately, I don't know the author, but agreed it reads more like a pop sci book. Although I only hope to write as coherently as that when I'm 96 y/o.
Not if some properties are unexpectedly emergent. Then it is science. For instance, why should a generic statistical model be able to learn how to fill in blanks in text using a finite number of samples? And why should a generic blank-filler be able to produce a coherent chat bot that can even help you write code?
Some have even claimed that statistical modelling shouldn't able to produce coherent speech, because it would need impossible amounts of data, or the optimisation problem might be too hard, or because of Goedel's incompleteness theorem somehow implying that human-level intelligence is uncomputable, etc. The fact that we have a talking robot means that those people were wrong. That should count as a scientific breakthrough.
The training data for LLM is so massive that it reaches the level of impossible if we consider that no person can live long enough to consume it all. Or even a small percent of it.
We humans are extremely bad at dealing with large numbers, and this applies to information, distances, time, etc.
That's not a good argument. Neuroscience was constructed by (other) brains. The brain is trying to explain itself.
> The truth is that all of the progress on machine learning is absolutely science.
But not much if you're interested in finding out how our brain works, or how language works. One of the interesting outcomes of LLMs is that there apparently is a way to represent complex ideas and their linguistic connection in a (rather large) unstructured state, but it comes without thorough explanation or relation to the human brain.
> Chomsky is [...] pretty flippant about what this stuff can do.
True, that's his style, being belligerently verbose, but others have been pretty much fawning and drooling over a stochastic parrot with a very good memory, mostly with dollar signs in their eyes.
This is not relevant. An observer who deceives for purposes of “balancing” other perceived deceptions is as untrustworthy and objectionable as one who deceives for other reasons.
To be fair the article is from two years ago, which when talking about LLMs in this age arguably does count as "old", maybe even "really old".
I remember having thoughts like this until I listened to him talk on a podcast for 3 hours about chatGPT.
What was most obvious is Chomsky really knows linguistics and I don't.
"What Kind of Creatures Are We?" is good place to start.
We should take having Chomsky still around to comment on LLMs as one of the greatest intellectual gifts.
Much before listening to his thoughts on LLMs was me projecting my disdain for his politics.
I've been saying this my whole life, glad it's finally catching on
It is not science, which is the study of the natural world. You are using the word "science" as an honorific, meaning something like "useful technical work that I think is impressive".
The reason you are so confused is that you can't distinguish studying the natural world from engineering.
He's not able to communicate anymore, so we get that one for free.
> Again, we’d laugh. Or should.
Should we? This reminds me acutely of imaginary numbers. They are a great theory of numbers that can list many numbers that do 'exist' and many that can't possibly 'exist'. And we did laugh when imaginary numbers were first introduced - the name itself was intended as a derogatory term for the concept. But who's laughing now?
The term “imaginary number” was coined by Rene Descartes as a derogatory and the ill intent behind his term has stuck ever since. I suspect his purpose was theological rather than mathematical and we are all the worse for it.
This is what Chomsky always wanted ai to be... especially language ai. Clever solutions to complex problems. Simple once you know how they work. Elegant.
I sympathize. I'm a curious human. We like elegant, simple revelations that reveal how out complex world is really simple once you know it's secrets. This aesthetic has also been productive.
And yet... maybe some things are complicated. Maybe LLMs do teach us something about language... that language is complicated.
So sure. You can certainly critique "ai blogosphere" for exuberance and big speculative claims. That part is true. Otoh... linguistics is one of the areas that ai based research may turn up some new insights.
Overall... what wins is what is most productive.
It certainly teaches us many things. But an LLM trained on as many words (or generally speaking an AI trained on sounds) in similar quantities of a toddler learning to understand, parse and apply language, would not perform well with current architectures. They need orders of magnitude more training material to get even close. Basically, current AI learns slowly, but of course it’s much faster in wall clock time because it’s all computer.
What I mean is: what makes an ALU (CPU) better than a human at arithmetic? It’s just faster and makes fewer errors. Similarly, what makes Google or Wikipedia better than an educated person? It’s just storing and helping you access stored information, it’s not magic (anymore). You can manually do everything mechanically, if you’re willing to waste the time to prove a point.
An LLM does many things better than humans, but we forget they’ve been trained on all written history and have hundreds of billions of parameters. If you compare what an LLM can do with the same amount of training to a human, the human is much better even at picking up patterns – current AIs strongest skill. The magic comes from the unseen vast amounts of training data. This is obvious when using them – stray just slightly outside of the training zone to unfamiliar domains and ”ability” drops rapidly. The hard part is figuring out these fuzzy boundaries. How far does interpolating training data get you? What are the highest level patterns are encoded in the training data? And most importantly, to what extent do those patterns apply to novel domains?
Alternatively, you can use LLMs as a proxy for understanding the relationship between domains, instead of letting humans label them and decide the taxonomy. One such example is the relationship between detecting patterns and generating text and images – it turns out to be more or less reversible through the same architecture. More such remarkable similarities and anti-similarities are certainly on the horizon. For instance, my gut feeling says that small talk is closer to driving a car but very different from puzzle solving. We don’t really have a (good) taxonomy over human- or animal brain processes.
But what we're good as using all of our capabilities to transform the world around us according to an internal model that is partially shared between individuals. And we have complete control over that internal model, diverging from reality and converging towards it on whims.
So we can't produce and manipulate text faster, but rarely the end game is to produce and manipulate text. Mostly it's about sharing ideas and facts (aka internal models) and the control is ultimately what matters. It can help us, just like a calculator can help us solve an equation.
EDIT
After learning to draw, I have that internal model that I switch to whenever I want to sketch something. It's like a special mode of observation, where you no longer simply see, but pickup a lot of extra details according to all the drawing rules you internalized. There's not a lot, they're just intrinsically connected with each other. The difficult part is hand-eye coordination and analyzing the divergences between what you see and the internal model.
I think that's why a lot of artists are disgusted with AI generators. There's no internal models. Trying to extract one from a generated picture is a futile exercice. Same with generated texts. Alterations from the common understanding follows no patterns.
A calculator is consistent and doesn’t “hallucinate” answers to equations. An LLM puts an untrustworthy filter between the truth and the person. Google was revolutionary because it increased access to information. LLMs only obscure that access, while pretending to be something more.
Also I used it for a few programming tasks I was pretty sure was in the datasets (how to draw charts with python and manipulate pandas frame). I know the domain, but wasn't in the mood to analyse the docs to get the implementation information. But the information I was seeking was just a few lines of sample code. In my experience, anything longer is pretty inconsistent and worthless explanations.
For Chomsky specifically, the entire existence of LLM, however it's framed, is a massive middle finger to him and a strike-through on a large part of his academic career. As much as I find his UG theory and its supporters irritating, it might be felt a bit unfair to someone his age.
Usually what happens is the information bubble bursts, and gets corrected, or it just fades out.
I was quite dismissive of him on LLMs until I realized the utter hubris and stupidity of dismissing Chomsky on language.
I think it was someone asking if he was familiar with the Wittgenstein Blue and Brown books and of course because he as already an assistant professor at MIT when they came out.
I still chuckle at my own intellectual arrogance and stupidity when thinking about how I was dismissive of Chomsky on language. I barely know anything and I was being dismissive of one of unquestionable titans and historic figures of a field.

But at least he admits that:

Isn't AI optimism an ideological motivation? It's a spectrum, not a mental model.
They're firmly on one extreme end of the spectrum. I feel as though I'm somewhere in between.
An equivalent observation might be that the only people who seem really, really excited about current AI products are grifters who want to make money selling it. Which looks a lot like Blockchain to many.
The perception on the left is that once again, corporations are foisting products on us that nobody wants, with no concern for safety, privacy, or respect for creators.
For better or worse, the age of garage-tech is mostly dead and Tech has become synonymous with corporatism. This is especially true with GenAI, where the resources to construct a frontier model (or anything remotely close to it) are far outside what a hacker can afford.
The deepest of deep ironies: I talk to people all the time talking about ushering in an age of post-capitalism and ignoring AI. When I personally can't see how the AI of the next decade and capitalism can coexist, the latter being based on human labor and all. Like, AI is going to be the reason what you want is going to happen, so why ignore it?
That framing may be true within tech circles, not the broader political divide. "Hackers" aren't collectively discounting and ignoring AI tools regardless of their enthusiasm for open-source.
Safety-ism is also most popular among those see useful potential in AI, and a generous enough timeline for AGI.
Understanding Linguistics before LLMs:
“We think Birds fly by flapping their wings”
Understanding Linguistics Theories after LLMs:
“Understanding the physics of Aerofoils and Bernoulli’s principle mean we can replicate what birds do”
Not that I am an LLM zealot. Frankly, some of the clear trajectory it puts humans on makes me question our futures in this timeline. But even if I am not a zealot, but merely an amused, but bored middle class rube, the serious issues with it ( privacy, detailed personal profiling that surpasses existing systems, energy use, and actual power of those who wield it ), I can see it being implemented everywhere with a mix of glee and annoyance.
I know for a fact it will break things and break things hard and it will be people, who know how things actually work that will need to fix those.
I will be very honest though. I think Chomsky is stuck in his internal model of the world and unable to shake it off. Even his arguments fall flat, because they don't fit the domain well. It seems like they should given that he practically made his name on syntax theory ( which suggests his thoughts should translate well into it ) and yet.. they don't.
I have a minor pet theory on this, but I am still working on putting it into some coherent words.
If you're only going to read one part, I think it is this:
It is easy to look at metrics of performance and call things solved. But there's much more depth to these problems than our abilities to solve some task. It's not about just the ability to do something, the how matters. It isn't important that we are able to do better at navigating than birds or insects. Our achievements say nothing about what they do.This would be like saying we developed a good algorithm only my looking at it's ability to do some task. Certainly that is an important part, and even a core reason for why we program in the first place! But its performance tells us little to nothing about its implementation. The implementation still matters! Are we making good uses of our resources? Certainly we want to be efficient, in an effort to drive down costs. Are there flaws or errors that we didn't catch in our measurements? Those things come at huge costs and fundamentally limit our programs in the first place. The task performance tells us nothing about the vulnerability to hackers nor what their exploits will cost our business.
That's what he's talking about.
Just because you can do something well doesn't mean you have a good understanding. It's natural to think the two relate because understanding improves performance that that's primarily how we drive our education. But this is not a necessary condition and we have a long history demonstrating that. I'm quite surprised this concept is so contentious among programmers. We've seen the follies of using test driven development. Fundamentally, that is the same. There's more depth than what we can measure here and we should not be quick to presume that good performance is the same as understanding[0,1]. We KNOW this isn't true[2].
I agree with Chomsky, it is laughable. It is laughable to think that the man in The Chinese Room[3] must understand Chinese. 40 years in, on a conversation hundreds of years old. Surely we know you can get a good grade on a test without actually knowing the material. Hell, there's a trivial case of just having the answer sheet.

He alludes to quite a bit here - impossible languages, intrinsic rules that don’t actually express in the language, etc - that leads me to believe there’s a pretty specific sense by which he means “understanding,” and I’d expect there’s a decent literature in linguistics covering what he’s referring to. If it’s a topic of interest to you, chasing down some of those leads might be a good start.
(I’ll note as several others have here too that most of his language seems to be using specific linguistics terms of art - “language” for “human language” is a big tell, as is the focus on understanding the mechanisms of language and how humans understand and generate languages - I’m not sure the critique here is specifically around LLMs, but more around their ability to teach us things about how humans understand language.)
If we define "understanding" like "useful", as in, not an innate attribute, but something in relation to a goal, then again, a good imitation, or a rudimentary model can get very far. ChatGPT "understood" a lot of things I have thrown at it, be that algorithms, nutrition, basic calculations, transformation between text formats, where I'm stuck in my personal development journey, or how to politely address people in the email I'm about to write.
>What if our „understanding“ is just unlocking another level in a model?
I believe that it is - that understanding is basically an illusion. Impressions are made up from perceptions and thinking, and extrapolated over the unknown. And just look how far that got us!
I would say that it is to what extent your mental model of a certain system is able to make accurate predictions of that system's behavior.
I found this out when attempting to transform wiki pages into blog-specific-speak, repeatedly.
In this article he is very focused on science and works hard to delineate science (research? deriving new facts?) from engineering (clearly product oriented). In his opinion ChatGPT falls on the engineering side of this line: it's a product of engineering, OpenAI is concentrating on marketing. For sure there was much science involved but the thing we have access to is a product.
IMHO Chomsky is asking: while ChatGPT is a fascinating product, what is it teaching us about language? How is it advancing our knowledge of language? I think Chomsky is saying "not much."
Someone else mentioned embeddings and the relationship between words that they reveal. Indeed, this could be a worthy area of further research. You'd think it would be a real boon when comparing languages. Unfortunately the interviewer didn't ask Chomsky about this.
For other commentators, as I understand it, Chomsky's talking about well-defined grammar and language and production systems. Think Hofstadter's Godel Escher Bach. Not "folk" understanding of language.
I have no understanding or intuition, or even a finger nail grasp, for how an LLM generates, seemingly emulating, "sentences", as though created with a generative grammar.
Is any one comparing and contrasting these two different techniques? Being noob, I wouldn't even know where to start looking.
I've gleaned that someone(s) are using LLM/GPT to emit abstract syntax trees (vs a mere stream of tokens), to serve as input for formal grammars (eg programming source code). That sounds awesome. And something I might some day sorta understand.
I've also gleaned that, given sufficient computing power, training data for future LLMs will have tokenized words (vs just character sequences). Which would bring the two strategies closer...? I have no idea.
(Am noob, so forgive my poor use of terminology. And poor understanding of the tech, too.)
I don't follow. Aren't those entirely separate things? The most accurate models of anything necessarily account for the underlying mechanisms. Perhaps I don't understand what you mean by "explanatory"?
Specifically in the case of deep neural networks, we would generally suppose that it had learned to model the underlying reality. In effect it is learning the rules of a sufficiently accurate simulation.
But they don't necessarily convey understanding to humans. Prediction is not explanation.
There is a difference between Einstein's General Theory of Relativity and a deep neural network that predicts gravity. The latter is virtually useless for understanding gravity (that's even if makes better predictions).
> Specifically in the case of deep neural networks, we would generally suppose that it had learned to model the underlying reality. In effect it is learning the rules of a sufficiently accurate simulation.
No, they just fit surface statistics, not underlying reality. Many physics phenomena were predicted using theories before they were observed, they would not be in the training data even though they were part of the underlying reality.
I would dispute this claim. I would argue that as models become more accurate they necessarily more closely resemble the underlying phenomena which they seek to model. In other words, I would claim that as a model more closely matches those "surface statistics" it necessarily more closely resembles the underlying mechanisms that gave rise to them. I will admit that's just my intuition though - I don't have any means of rigorously proving such a claim.
I have yet to see an example where a more accurate model was conceptually simpler than the simplest known model at some lower level of accuracy. From an information theoretic angle I think it's similar to compression (something that ML also happens to be almost unbelievably good at). Related to this, I've seen it argued somewhere (I don't immediately recall where though) that learning (in both the ML and human sense) amounts to constructing a world model via compression and that rings true to me.
> Many physics phenomena were predicted using theories before they were observed
Sure, but what leads to those theories? They are invariably the result of attempting to more accurately model the things which we can observe. During the process of refining our existing models we predict new things that we've never seen and those predictions are then used to test the validity of the newly proposed models.
But even so,
> In other words, I would claim that as a model more closely matches those "surface statistics" it necessarily more closely resembles the underlying mechanisms that gave rise to them.
I don't what it means, for example, for a deep neural network, to "more resemble" the underlying process of the weather. It's also obviously false in general: If you have a mechanical clock and quartz-crystal analog clock you are not going to be able to derive the internal workings of either or distinguish between them from the hand positions. The same is true for two different pseudo-random number generator circuits that produce the same output.
> I have yet to see an example where a more accurate model was conceptually simpler than the simplest known model at some lower level of accuracy.
I don't understand what you mean. Simple models often yield a high level of understanding without being better predictors. For example an idealized ball rolling down a plane, Galileo's mass/gravity thought experiment, Kepler etc. Many of these models ignore less important details to focus on the fundamental ones.
> From an information theoretic angle I think it's similar to compression (something that ML also happens to be almost unbelievably good at). Related to this, I've seen it argued somewhere (I don't immediately recall where though) that learning (in both the ML and human sense) amounts to constructing a world model via compression and that rings true to me.
In practice you get nowhere trying to recreate the internals of a cryptographic pseudo-random number generator from the output it produces (maybe in theory you could do it with infinite data and no bounds on computational complexity or something) even though the generator itself could be highly compressed.
> Sure, but what leads to those theories? They are invariably the result of attempting to more accurately model the things which we can observe.
Yes but if the model does not lead to understanding you cannot come up with the new ideas.
That said, I'm inclined to object to this "explanatory" characteristic you're putting forward. We as humans certainly put a lot of work into optimizing the formulation of our models with the express goal of easing human understanding but I'm not sure that's anything more than an artifact of the system that produces them. At the end of the day they are tools for accomplishing some purpose.
Perhaps the idea you are attempting to express is analogous to concepts such as principal component analysis as applied to the representation of the final model?
> If you have a mechanical clock and quartz-crystal analog clock you are not going to be able to derive the internal workings of either or distinguish between them from the hand positions.
Arguably modern physics analogously does exactly that, although the amount of resources required to do so is astronomical.
Anyhow my claim was not about the ability or lack thereof to derive information from the outputs of a system. It was that as you demand increased accuracy from a model of the hand positions (your example) you will be necessarily forced to model the internal workings of the original physical system to increasingly higher fidelity. I claim that there is no way around this - that fundamentally your only option for increasing the accuracy of the output of a model is for it to more closely resemble the inner workings of the thing being modeled. Taken to the (notably impossible) extreme this might take the form of a quantum mechanics based simulation of the entire system.
Extrapolating this to the weather, I'm claiming that any reasonably accurate ML model will necessarily encompass some sort of underlying truth about the physical system that it is modeling and that as it becomes more accurate it will encode more such truth. Notably, I make no claim about the ability of an unaided human to interpret such truths from a binary blob of weights.
> I don't understand what you mean. Simple models often yield a high level of understanding without being better predictors.
I said nothing about efficiency of educating humans (ie information gathering by or transfer between agents) but rather about model accuracy versus model complexity. I am claiming that more accurate models will invariably be more complex, and that said complexity will invariably encode more information about the original system being modeled. I have yet to encounter a counterexample.
> [CSPRNG recreation]
It is by design impossible to "model" the output of such a function in a bitwise accurate manner without reproducing the internals with perfect fidelity. In the event that someone figures out how to model the output in an imprecise manner without access to the key that would generally be construed as the algorithm having been broken. In other words that example aligns perfectly with my point in the sense that it cannot be approximated to any degree better than random chance with a "simpler" (ie less computationally complex than the original) mechanism. It takes the continuum of accuracy that I was originally describing and replaces it with a step function.
> Yes but if the model does not lead to understanding you cannot come up with the new ideas.
I suppose human understanding is a prerequisite to new human constructed models but my (counter-)point remains. Physics theories are "nothing more" than humans fitting "surface statistics" to increasing degrees of accuracy. I think this is a fairly fundamental truth with regards to the philosophy of science.
Chomsky talks about how the current approach can't tell you about what humans are doing, only approximate it; the example he has given in the past is taking thousands of hours of footage of falling leaves and then training a model to make new leaf falling footage versus producing a model of gravity, gas mechanics for the air currents, and air resistance model of leaves. The later representation is distilled down into something that tells you about what is happening at the end of some scientific inquiry, and the former is a opaque simulation for engineering purposes if all you wanted was more leaf falling footage.
So I interpret Chomsky as meaning "Look, these things can be great for an engineering purpose but I am unsatisfied in them for scientific research because they do not explain language to me" and mostly pushing back against people implying that the field he dedicated much of his life to is obsolete because it isn't being used for engineering new systems anymore, which was never his goal.
He wants to understand how human language works. If I get him right — and I'm absolutely sure that I don't in important ways — then LLMs are not that interesting because both (1) and (2) above are true of them.
I’m perfectly willing to bet that there are LLMs that can pass a Turing test, even against a mind like Chomsky.
I understand his diction is a bit impenetrable but I believe the intention is to promote literacy and specificity, not just to be a smarty-pants.
Quoting Chomsky:
> These considerations bring up a minor problem with the current LLM enthusiasm: its total absurdity, as in the hypothetical cases where we recognize it at once. But there are much more serious problems than absurdity.
> One is that the LLM systems are designed in such a way that they cannot tell us anything about language, learning, or other aspects of cognition, a matter of principle, irremediable... The reason is elementary: The systems work just as well with impossible languages that infants cannot acquire as with those they acquire quickly and virtually reflexively.
Response from o3:
LLMs do surface real linguistic structure:
• Hidden syntax: Attention heads in GPT-style models line up with dependency trees and phrase boundaries—even though no parser labels were ever provided. Researchers have used these heads to recover grammars for dozens of languages.
• Typology signals: In multilingual models, languages that share word-order or morphology cluster together in embedding space, letting linguists spot family relationships and outliers automatically.
• Limits shown by contrast tests: When you feed them “impossible” languages (e.g., mirror-order or random-agreement versions of English), perplexity explodes and structure heads disappear—evidence that the models do encode natural-language constraints.
• Psycholinguistic fit: The probability spikes LLMs assign to next-words predict human reading-time slow-downs (garden-paths, agreement attraction, etc.) almost as well as classic hand-built models.
These empirical hooks are already informing syntax, acquisition, and typology research—hardly “nothing to say about language.”
It's completely irrelevant because the point he's making is that LLMs operate differently from human languages as evidenced by the fact that they can learn language structures that humans cannot learn. Put another way, I'm sure you can point out an infinitude of similarities between human language faculty and LLMs but it's the critical differences that make LLMs not useful models of human language ability.
> When you feed them “impossible” languages (e.g., mirror-order or random-agreement versions of English), perplexity explodes and structure heads disappear—evidence that the models do encode natural-language constraints.
This is confused. You can pre-train an LLM on English or an impossible language and they do equally well. On the other hand humans can't do that, ergo LLMs aren't useful models of human language because they lack this critical distinctive feature.
https://arxiv.org/abs/2401.06416
The reason the Moro languages are of interest are that they are computationally simple so it's a puzzle why humans can't learn them (and no surprise that LLMs can). The authors of the paper miss the point and show irrelevant things like there exist complicated languages that both humans and LLMs can't learn.
https://news.ycombinator.com/item?id=42290482
It's impressive that LLMs can learn languages that humans cannot. In what frame is this a negative?
Separately, "impossible language" is a pretty clear misnomer. If an LLM can learn it, it's possible.
That's what "impossible language" means in this context, not something like computationally impossible or random.
As I said in another comment this whole dispute would be put to bed if people understood that they don't care about what humans do (and that Chomsky does).
It's completely unremarkable that humans are unable to learn certain languages, and soon it will be unremarkable when humans have no cognitive edge over machines.
Response: Science? "Ancient Linguistics" would more accurately describe Chomsky's field of study and its utility
If science is irrelevant to you it's you who should have recognized this before spouting off.
By whom?
As this is Hacker News, it is worth mentioning that he developed the concept of context-free grammars. That is something many of us encounter on a regular basis.
No matter what personality flaws he might have and how misguided some of his political ideas might be, he is one of the big thinkers of the 20th century. Very much unlike Trump.
Perhaps it is more important to know the limitations of tools rather than dismiss their utility entirely due to the existence of limitations.
> Perhaps it is more important to know the limitations of tools rather than dismiss their utility entirely due to the existence of limitations.
Well, yes. And "reasoning" is only something LLMs do coincidentally, to their function as sequence continuation engines. Like performing accurate math on rationale numbers, it can happen if you put in a lot of work and accept a LOT of expensive computation. Even then there exists computations that just are not reasonable or feasible.
Reminding folks to dismiss the massive propaganda engine pushing this bubble isn't "dismissing their utility entirely".
These are not reasoning machines. Treating them like they are will get you hurt eventually.
Can they reason? Maybe, depending on your definition of reasoning.
An example: which weighs more a pound of bricks and 453.59 grams of feathers? Explain your reasoning.
LLM: The pound of bricks weighs slightly more.
*Reasoning:*
* *1 pound* is officially defined as *0.45359237 kilograms*, which is *453.59237 grams*. * You have *453.59 grams* of feathers.
So, the pound of bricks (453.59237 grams) weighs a tiny fraction more than the 453.59 grams of feathers. For most practical purposes, they'd be considered the same, but technically, the bricks are heavier by 0.00237 grams. /llm
It is both correct and the reasoning is sound. Do I understand that the machine is a pattern following machine, yes! Is there an argument to be made that humans are also that? Probably. Chomsky himself argued in favor of a universal grammar, after all.
I’m steel manning this a bit, but the point is that LLMs are capable of doing some things which are indistinguishable from human reasoning in terms of results. Does the process matter in all cases?
An attempt: They are bad reasoning machines that already are useful in a few domains and they're improving faster than evolutionary speeds. So even if they're not useful today in a domain relevant to you there's a significant possibility they might be in a few months. AlphaEvolve would have been scifi a decade ago.
"It's like if a squirrel started playing chess and instead of "holy shit this squirrel can play chess!" most people responded with "But his elo rating sucks""
Care to expand on how his theories can be taught in such a binary way?
This leads to people who agree hiring each other and departments ‘circling the wagon’ on these issues. You’ll see this referred to as east vs west coast, but it’s not actually that clearly geographically delineated.
So anyways, these are open questions that people do seriously discuss and study, but the politics of academia make it difficult and unfortunately this often trickles down to students.

But generally speaking Chomsky's ideas, and in particular, the Universal Grammar are no longer in vogue.
