> To accomplish that feat, the treatment is wrapped in fatty lipid molecules to protect it from degradation in the blood on its way to the liver, where the edit will be made. Inside the lipids are instructions that command the cells to produce an enzyme that edits the gene. They also carry a molecular GPS — CRISPR — which was altered to crawl along a person’s DNA until it finds the exact DNA letter that needs to be changed.

That is one of the most incredible things I have ever read.

One other fun part of gene editing in vivo is that we don't actually use GACU (T in DNA). It turns out that if you use Pseudouridine (Ψ) instead of uridine (U) then the body's immune system doesn't nearly alarm as much, as it doesn't really see that mRNA as quite so dangerous. But, the RNA -> Protein equipment will just make protiens it without any problems.

Which, yeah, that's a miraculous discovery. And it was well worth the 2023 Nobel in Medicine.

Like, the whole system for gene editing in vivo that we've developed is just crazy little discovery after crazy little discovery. It's all sooooo freakin' cool.

I remember from a few few years back that the lipid coating may have caused problems for the liver, when treating people for diseases that needed to target a lot of tissue, such as muscle disorders. Is that still the case?
Teever · 2h ago
I suppose a downside (depending on your perspective) of this is that it will make people who are genetically modified in this fashion trivial to detect.

That's good if your goals are to detect genetic modification which may be considered cheating in competitive sports.

That's bad if your goals are to detect genetically modified people and discriminate against them.

I see a near future where the kind of people who loathe things like vaccines and genuinely believe that vaccines can spread illness to the non-vaccinated feel the same way about other things like genetic modification and use legal mechanisms to discriminate and persecute people who are genetically modified.

ale42 · 2h ago
> it will make people who are genetically modified in this fashion trivial to detect.

I'm not totally sure. If I understand it correctly, the mRNA contains pseudouridine, and it makes the protein that will edit the DNA. The edited DNA should look like a normal one.

Teever · 2h ago
Ah. That makes sense. My mistake.
prisenco · 33m ago
I'm less interested in detecting genetic modification for the purposes of discrimination than making sure it's available to everyone.

Assuming requisite safety of course.

sfink · 58m ago
Careful with qualifiers there. I genuinely believe that vaccines can spread illness to the non-vaccinated, since it has happened many times and is well-documented. For example, it's why only the inactivated (aka "dead" virus) polio vaccine has been used in the US since 2000.

I'm not arguing about whether the risks of the attenuated virus outweigh the benefits. I think the data are very clear there. (Heh -- and I'm sure the vast majority of people will agree with that statement, even if they disagree on what the clear answer is....)

It's just that one shouldn't mock a belief without including the necessary qualifiers, as otherwise you're setting up an argument that can be invalidated by being shown to be factually incorrect.

As for genetic modification of humans, IMO there are a lot of very good reasons to be wary, most of them social. Fatal hereditary conditions are obviously an easy call. What about autism (not saying there's a genetic link there to use, just a what if)? Or other neurodivergence? Like being a troublemaker in class? Or voting for the party that doesn't control the medical incentive structure? Heck, let's stick with the fatal hereditary conditions, and say the editing does not affect germ cells. Is it ok if the human race gradually becomes dependent on gene editing to produce viable offspring? Or let's say it does extend to germ cells. The population with resources becomes genetically superior (eg in the sense of natural lifespan and lower medical costs) to those without, creating a solid scientific rationale for eugenics. Think of it as redlining carved into our blood.

I don't think discrimination against the genetically modified is the only potential problem here.

As humans, we'll deal with these problems the way we've dealt with everything else transformational. Namely: very, very badly.

catigula · 44m ago
I mean, I feel like autism is a terrible example here, it's not just some quirky personality trait, it's a reality people live with that runs the gamut from difficult to completely debilitating. Even the more mild forms of autism cause extreme difficulty in many aspects of life. If that was curable or preventable, that'd be great.

If it turns out some pathogen or chemical made me autistic, regardless of whether or not I could be cured as an adult, I'd have certainly preferred to live the reality where I had been as a child.

zmmmmm · 18s ago
I think a better reason autism is a bad example is that part of its definition is that it is a consequence of fundamental brain structure and development. These aren't things you will "undo" with some gene edits. The whole brain has developed in a different way. Short of re-growing them a new brain you aren't going to change that (assuming you wanted to).
sfink · 18m ago
Sure, the purpose was to illustrate a slippery slope, and curing autism is meant to be more obviously good than abolishing all forms of neurodivergence but less obviously good than fixing fatal hereditary diseases.

I'm not going to claim that I know the perfect place to draw the line.

LawrenceKerr · 1h ago
If you're going to make the comparison with vaccines, and if history is any indication, the more realistic worry would be the other way around (since that's where the money is): that genetic modifications will be mandated, and that those who object will be discriminated against.

[And no, I am not anti-vax, nor anti-gene-editing.]

> [...] then the body's immune system doesn't nearly alarm as much, as it doesn't really see that mRNA as quite so dangerous

Please tell me there are measures to prevent this going into the wild. Please tell me this won't be used in large-scale industrial farming.

Balgair · 53m ago
Yeah, it's not a drama.

The reason that the body doesn't alarm as much to Pseudouridine, is that it's not a 'natural' RNA base. Meaning that, for the most part, nature really never uses it and so we haven't evolved to look out for it. Nature uses Uridine and so immune systems have evolved to look out for random bits of RNA in the body that use it and then clean that all up.

It's like if you're looking to clean up legos in you house with a romba that only cleans up legos. And all of a sudden it finds a duplo. It's going to take a hot second to figure out what to do with the duplo. And in that time, you can sneak by and build a duplo fort. (Look, I know this analogy is bad, but it's the best I can come up with on the fly, sorry. If anyone else wnats to come up with a better one, please do!).

The Pseudouridine is used up and degraded very quickly inside the cell, minutes at the very very longest, more like microseconds. It's just part of a messenger (the 'm' in 'mRNA') to tell the cell to do things.

You might see mRNA gene editing in factory farms, but it would just be easier to do germline editing instead and skip spraying animals, plants, and fungi. Why waste the equipment, right?

abracadaniel · 46m ago
As I understand it, there is nothing in nature that can create it, so the mRNA can never be accidentally replicated. It’s a safety mechanism that prevents escape.

Farming? This will be used in warfare.
Muromec · 20s ago
That would be less effective than bio and chemical weapons are. Which are not used because they just suck
Balgair · 46m ago
Not under the current way we do things, I don't imagine.

So the real trick here isn't the mRNA, it's the nanobubbles. Basically, you're putting these bits of mRNA into these little fat bubbles and then injecting those into the blood. Making those bubble shelf stable is really hard, hence the issues with temperature and the covid vaccine. To then make those little fat bubbles stable-ish in the blood is also a really hard thing to do. They have to get to the right places (in this baby's case, the liver) and then degrade there, drop off the mRNA, and not mess up other tissues all that much. Like, it's not terrible to make these micelles degrade in vivo, but to have them do that and not degrade in the tubes, ... wow... that is really difficult. There's a reason that Moderna is so highly valued, and it's these bubbles.

To try to then put these in a weapon that could do this though the airways would be, like, nearly impossible. Like, as in I think the second law of thermodynamics, let alone biology, and then simple industrial countermeasure like a N95 respirator, yeah, I think all of that makes it pretty much impossible to weaponize.

(Hedging my bets here: I don't know if they had to do all that with this baby, as you can kinda go from lab to baby really fast, since it's such a special case. But for mRNA based vaccines and cancer treatments, you have to deal with the shelf stable issue)

(Also, other bio people, yes, I am trying to explain to laymen here. Please chime in and tell me how I'm wrong here)

This isnt entirely unlike the method mRNA vaccines use. Through some clever biochemistry, mRNA vaccines get bits of code into cells where the cell's built in code compilers manufacture proteins that induce immunity.

We have developed software patches for our biology.

Gene therapies are pretty incredible. Some of them are still making a button-hole with a machete, but that's relative to the previous medical intervention of a button-hole with a tank's main gun.

One of the treatments for sickle-cell involves switching off the gene that makes the malfunctioning red blood cells, but of course that's not sufficient; you'd stop making red blood cells completely and you'd die. So it's combined with a modification that switches on a gene that all humans express pre-birth that causes your body to make "super-blood": red blood cells with significantly more binding points for oxygen. This is necessary because a fetus gets oxygen from its mother's blood, so the increased binding affinity is useful for pulling the oxygen towards the fetus at the placental interface. After birth, expression of that gene is disabled and regular RBC genes switch on.

So the therapy doesn't "fix" sickle RBCs; it disables the body's ability to make them and re-enables fetal RBCs! I have seen no literature on whether having fetal RBCs in adulthood has any benefits or drawbacks (besides changing the affinity ratio for their fetus if the patient gets pregnant, I imagine increased-affinity RBC could help for athletics... But I also imagine it requires more iron to generate them so has dietary impact).

nomadpenguin · 38m ago
High affinity RBCs would actually be a disadvantage for athletics. You actually don't need very high affinity to pick up oxygen from the lungs -- your lungs are comparatively extremely high in oxygen. What matters more is being able to drop the oxygen off in peripheral tissues. Higher affinity means that it's harder to actually deliver the oxygen, which is why we evolutionarily developed the switch away from fetal hemoglobin.

koeng · 2h ago
It's fundamentally different than a computer and arguably more complete.

The talk of "crawling along the genome" is kinda fundamentally wrong though and is a bit irking - CRISPR kinda just bumps around until it hits a PAM site, in which case it starts checking against sgRNA. Much more random than they make it seem

joshmarlow · 12m ago
If this thread interests you, you should check out "Blood Music" by Greg Bear. It's pretty old but the premise is that a researcher 'closes the loop' in a bunch of cells by making them able to edit their own DNA - thus making them Turing Complete.

Hilarity subsequently ensues.

Made me think of

    It was only in college, when I read Douglas Hofstadter’s Gödel, Escher, Bach, that I came to understand cells as recursively self-modifying programs. The language alone was evocative. It suggested that the embryo—DNA making RNA, RNA making protein, protein regulating the transcription of DNA into RNA—was like a small Lisp program, with macros begetting macros begetting macros, the source code containing within it all of the instructions required for life on Earth. Could anything more interesting be imagined?

This system isn't really turing complete, but existing biology provides everything required to make a computer which is Turing complete (assuming non-infinite tape size).

True programmatic biology is still very underdeveloped. I have seen logic gates, memory, and state machines all implemented, but I don't think anybody has built somethign with a straightforward instruction set, program counter, addressable RAM, and registers that was useful enough to justify advanced research.

Robotbeat · 2h ago
Yeah, in some ways, the genetic code and molecular biology around transcription, etc, more closely resembles the abstract Turing Machine than an actual computer does. Absolutely fascinating that the messy world of biology ends up being pretty analogous to the clean world of binary logic. Gene sizes are expressed in kilobases, where a base carries 2 bits of information.

Really incredible story and I'd love to know the process for receiving this, for example FDA approval etc. It's nice to see such in-your-face results from Federal funding programs. Without being political, it's sometimes hard for regular people to appreciate just how much good actually comes out of Federal Funding. There was another thread where someone even said something along the lines of : "Well during war things get done faster" . This simply isn't true. It might be done louder but Federal Funding never stopped pushing things forward.

jjeaff · 6m ago
I'm not an expert, but I have learned that FDA approval is not actually necessary for treatments and drugs. Your doctor has a lot of leeway when it comes to treatment but she of course experiences more risk of accusations of malpractice when prescribing off label drugs or unapproved treatments. insurance will also rarely cover treatment that is not FDA approved. the requirement for FDA approval generally has more to do with your legal ability to market the drug, treatment, or product.

NYT isn’t super specific here, but they made it sound like the disease treated is liver related. My understanding is that the liver is a good place to start with CRISPR-type gene treatments, in that the liver normally deals with anomalous shit in your bloodstream, say, like CRISPR type edits. So anywhere outside the liver is going to be significantly harder to get really broad uptake of gene edits.

It’s crazy encouraging that this worked out for this kid, and I’m somewhat shocked this treatment was approved in the US - I don’t think of us as very aggressive in areas like this. But to me, really hopeful and interesting.

cdcox · 1h ago
You are right, current CRISPR systems tends to accumulate in the liver. Most CRISPR companies have shifted their focus to the liver over time because it's easiest to deliver there. Most viruses people use to target other organs are not large enough to carry CRISPR and lipid nanoparticles with CRISPR seem to like ending up in the liver and are hard to deliver at dose to hit other organ systems. It has been one of the big struggles of CRISPR companies. That being said, this is a huge deal and very encouraging.

As to the FDA stance, it tends to be more willing to go ahead with compassionate uses like this when it's clearly life or death.[1]

derektank · 1h ago
I hate to break it to you, but it will be substantially more difficult to target other organ systems. The liver is uniquely easy to target with our current vectors.

Right off the bat, the liver receives roughly a quarter of all cardiac output, either directly or second hand from the digestive organs. Additionally, the liver has a fenestrated endothelium which, while not completely unique in the body, uniquely allows molecules like lipid nanoparticles (LNPs) to access liver cells. Finally, the liver is the site of most lipoprotein processing, and LNPs can be designed to take advantage of the existing pathways to get the gene editing mRNA into the hepatocytes. All this is to say that if you have a genetic condition that primarily effects the liver, there's a lot more hope for treatment in the near term than for others.

Good lecture on the difficulties of finding appropriate platforms for delivering gene therapies to cells for anyone interested [1]

No they were not. A vaccine triggers an immune response, not a functional change.

mRNA vaccines are highly localized: you get a sore arm because most of it only gets taken up by muscle cells around the injection site, which spend some time producing the antigen and triggering a primary immune response (the inflammation aka the sore arm).

I wonder if this also affects germline cells so he won't pass the same disease on to his children.

>KJ has made medical history. The baby, now 9 ½ months old, became the first patient of any age to have a custom gene-editing treatment, according to his doctors.

This is _not_ the first human to be treated with a treatment under the wide umbrella of gene therapy based on their own edited genes. There probably is a more narrow first here but the technical details get lost in journalism which is a shame.

jfarlow · 3h ago
"Custom" in that this therapy was designed AFTER a specific patient showed a need, and then given to _that_ patient. In most every other context a particular class of disease is known, a drug designed, and then patients sought that have that disease that matches the purpose of the drug.

What's intriguing is not the 'custom' part, but the speed part (which permits it to be custom). Part of what makes CRISPR so powerful is that it can easily be 'adjusted' to work on different sequences based on a quick (DNA) string change - a day or two. Prior custom protein engineering would take minimum of months at full speed to 'adjust'.

That ease of manipulating DNA strings to enable rapid turnaround is similar to the difference between old-school protein based vaccines and the mRNA based vaccines. When you're manipulating 'source code' nucleic acid sequences you can move very quickly compared to manipulating the 'compiled' protein.

I want to say, maybe it's better to say first human under proper IRB/regulatory compliance. Some rogue academic in China tried it a few years ago, if I recall, but with absolutely no oversight and he was pilloried. Also I don't think there is much details about what he actually did...

dekhn · 2h ago
What the Chinese guy (He) did was completely different. He permanently altered the germline in embryos, which means that every cell in the resulting baby is transformed permanently with the change he made. The work he did violated a wide range of good practice (specifically, the change he made didn't actually work for the goal he desired, and he also ignored all the ethical advice around this experiment, and avoided getting the necessary approvals).

This research is instead a therapy used to treat an already born baby, and it doesn't modify all the cells in the body. Many cells in the body that are transformed by this technique will eventually die and be replaced by clones of stem cells which weren't transformed. I haven't read in detail about whether this therapy targets stem cells, and how long term effective the treatment will be- hepatocytes (liver cells) turn over constantly, so I would expect if the treatment did not affect the hepatocyte stem cells, it would only last ~months and the treatment would have to be repeated.

Are the edited genes inherited, or the original ones? Does the previous question have an answer that depends on the babies sex?

From an evolutionary perspective it‘s interesting how the further medicine gets, the more we inherit genes unfit for life without medical support.

Balgair · 2h ago
No, it's only in the liver, from what I can tell from the science, not the gametes.

No, it would not depend on the sex of the baby, as the chromosomes that you're editing aren't X or Y.

Evolutionarily, the inheritance of genes is a far slower process than the medical advancements we make, so what I think we're seeing here is a chasing down of the low probability events. In that, most of the evolutionary pressure is coming from things like dirty water and bad food, but as we're solving those low hanging fruit, we have to go to lower probability events to make progress that feels equally important.

Also, if I am wrong here on the answers to the questions, please correct me!

dekhn · 2h ago
If they could get complete delivery to the liver stem cells, then the change could be permanent, although this is making many simplifications.

Organs in your body usually keep some very old cells (formed in the embryo) around which act as parents for all the new cells in an organ. Any cell can only divide a limited number of times, so they typically maintain a "tree structure" where the old cells create children and grandchildren (etc) that then differentiate into the organ-specific cells that do the actual organ work.

If you modify only the differentiated cells, eventually they die, and are replaced by descendents of stem cells; if those stem cells didn't get modified, their descendents will not have the fix, and the treatment efficacy reduces over time.

A Chinese scientist claimed that he did CRISPR on twins back in 2018. https://www.science.org/content/article/crispr-bombshell-chi...

He was jailed for illegal medical practices but it seemed like he established a proper lab after serving the sentence and hopefully he is focused on less objectionable practices. https://www.npr.org/2023/06/08/1178695152/china-scientist-he...

From a purely utilitarian perspective, funding research like this is not an effective use of dollars at the margin. How many people could we save if an equivalent amount was put into reducing obesity, smoking, and drinking? How many people could we save if we stopped spending money we don't have to do things that the government isn't competent at allocating anyways?

That's not to say the research itself is not impressive nor important, but think critically about the fact that this money doesn't exist in a vacuum.

I think you may be operating under the assumption that the extremely expensive price tag will need to be repeated for each patient.

In reality, as this process becomes more mature it is going to become inexpensive.

The reduction in cost will almost certainly be similar to reduction in cost needed to sequence an individual's genome, which has fallen from tens of millions to hundreds of dollars.

The only catch is that we have to spend money to get there.

Another catch is that the nations who underwrite this research will turn millions in investments into trillions in dividends and the stingy or poor will be left in the cold.

Seeing that private enterprise is only good at taking publicly-funded work and patenting it, and that in the absence of public funding nothing ever gets invented, we should be all-in on this.

edit: it's apropos that you mentioned obesity because GLP-1 drugs are the direct, irrefutable, product of spending at government labs.

There's no evidence to support that gene therapy will ever be inexpensive. We can merely say that the process may become less shockingly expensive.

A similar thing has been said about so many cutting edge therapies and technologies in the past that I think you'll end up being quite surprised.

Eventually someone will invent a machine that spits these therapies out like espresso machines.

My prediction is based on the number of efforts, too numerous to list here, being undertaken to develop lab equipment to automate the extremely labor-intensive workflow and the accumulation of vast libraries of CRISPR-Cas9 screens and dependency maps, the creation of which are also expensive and labor-intensive.

I'm of accord with the Utopians of Ada Palmer's Too Like the Lightning:

When a Utopian dies, of anything, the cause is marked and not forgotten until solved. A fall? They rebuild the site to make it safe. A criminal? They do not rest until he is rendered harmless. An illness? It is researched until cured, regardless of the time, the cost, over generations if need be. A car crash? They create their separate system, slower, less efficient, costing hours, but which has never cost a single life. Even for suicide they track the cause, and so, patiently, blade by blade, disarm Death. Death, of course, has many weapons, and, if they have deprived him of a hundred million, he still has enough at hand to keep them mortal. For now.

It's super effective funding.

There are known DNA changes that would probably help all people with chronic diseases, but it's ethically more accepted to go for the more fatal diseases and cleaner cases first, like a rare mutation with a high fix rate.

That is not comparable at all. To save people from obesity, smoking and drinking, you don't need more resources on fundamental research. You need different education, and socio-economical programs, possibly even less funds on the overall: if no resources is spent anymore in promoting bad habits, you end up with more financial resources and a healthier population.

Instead if no resources is allocated on developing all the technical requirements to do such a thing, humanity ends up with less tools to heal itself, and that's it.

30 million people in the US are affected by "rare" genetic conditions.
dekhn · 2h ago
Yes, but the cures here aren't general. They're highly specific, and the rare conditions have a long tail- large numbers of different conditions, each with a very small population of affected individuals, and likely, the treatments will be somewhat customized for each type of disease.
pfisherman · 2h ago
See my comment above. Getting approval for rare diseases and expanding the indication to the common form of the disease is a well established strategy in pharma.
dekhn · 2h ago
yes, but that's totally different from coming up with a generalized treatment for a wide range of "rare" diseases.
pfisherman · 2h ago
Also rare genetic diseases give insight into the underlying mechanisms and pathology of common sporadic diseases, which can be leveraged to develop new and better therapies.

Getting a new drug or therapy approved for a rare form of a disease and then expanding the indication to the common disease patient population is a well established strategy.

caycep · 2h ago
a) that statement above has nothing to do with RFK

b) the whole point of NIH and other government research funds is to pay for this sort of "not clearly an effective use of dollars" type of research that Pfizer et al won't touch. but you can look at a ton of future applications from this - lipid packaging, CRISPR methods, drug delivery, etc that had to be devised, and could conceivably be commercially viable if the methodology is perfected and the cost comes down.

vjvjvjvjghv · 3h ago
With that line of thinking you would never do any advanced science.
jonplackett · 3h ago
I admit to having a similar thought to this - especially if it is then going to be commercialised and sold for millions of dollars per treatment.

BUT the long term view of creating a technology that can treat any genetic illness (or maybe even any illness?) must outweigh that _eventually_

This argument could be used to stop absolutely any research that isn't dirt cheap.

Maybe even the dirt cheap one, because even 100 dollars could go longer way somewhere in the Sahel.

jonhohle · 2h ago
I’ve thought about this recently as well and I don’t know if I have a fully developed view. What is the moral responsibility of all people to pay for medical research or operations that would affect a small number of people. Is it ethical to compel others to pay for the research deemed valuable by some, but not by others. Who is the arbiter of that research’s value?

I could say I believe the government should fund research into fixing people who think cilantro tastes like soap because for most of us it is delicious and promotes healthy diets. Should I be able to compel (tax) you to pay for that research?

Where that line is drawn will always be wrong to someone. How research is prioritized will always be wrong to someone. Is there an ethical way to determine the best use of collective resources and what portion of one’s property must be taken from them to fund that research.

> How many people could we save if an equivalent amount was put into reducing obesity, smoking, and drinking?

How confident are you the answer isn't very close to zero? We've already curtailed smoking quite a bit in the past 30 years. At the level of an individual, it isn't any particular mystery how to stop obesity or to simply not drink, but population-level interventions attempting to get people to voluntarily behave differently for their own health historically haven't worked well in these specific domains. Throwing more money at the problem doesn't seem like it would obviously change that.

Also keep in mind that overeating and alcohol addiction have significant genetic components. Research into gene editing has the eventual potential to cure damn near any disease, including whatever pet causes you personally think are worth defeating.

psychoslave · 2h ago

Said like that it paints things like there are not far more resources spent on propagating the bad habits (as some ROI is expected from this by some actors), and any attempt to put a social health program in history always ended in major catastrophes.

I completely disagree, the things you mentioned are all things which a person has a level of control over.

This is something beyond that, and is very valuable as this baby has no actual means of fighting this issue at all.

And who's to say this won't lead to fixing the other things anyway.

Great use of dollars

I think it was here a few years ago that I read a comment saying that sick children will be the Trojan horse for normalizing gene editing of humans, because who could say no to sick children, right? Well, guess it's here now, so how long utill the eugenics wars start?
jjcob · 2h ago
It's not a slippery slope. Fixing defects is rather straightforward, since it's usually a single gene that needs to be edited.

If you want make your baby smarter, taller, or more handsome, it's not so easy because these traits involve 1000s of genes.

For this reason I do not think that curying diseases will lead to designer babies.

sfink · 35m ago
If you can affect germline cells, then I don't see how it's not a slippery slope. (I'm not arguing against doing it, just that it is a slope and the slope is slippery.) No designer babies necessary.

I'll steelman "fixing defects" by sticking to serious hereditary diseases (and yes, only those that correspond to one or a few known genes). As more and more conditions become treatable, the population with access to resources will have lower healthcare costs by being less susceptible to problems. (Which is a good thing, note!) Insurance companies will have more and more proxies for differentiating that don't involve direct genetic information. Societally, "those people" [the poor and therefore untreated] cost more to support medically and are an increasing burden on the system. Eugenics gains a scientific basis. Do you want your daughter marrying someone genetically substandard, if you don't have the resources to correct any issues that might show up? Probably not, you're more likely to want to build a wall between you and them. Then throw over anyone who falls behind the bleeding edge of corrections.

It'll be the latest form of redlining, but this time "red" refers literally to blood.

it's unclear the outcome of this will be eugenics wars.

Answering the real question- it's unlikely these techniques will see widespread "recreational" usage any time soon, as they come with a wide range of risks. Further, the scientific community has learned a lot from previous eugenics programs; anything that happens in the future will happen with both social and political regulation.

It's ultimately hard to predict- many science fiction writers have speculated about this for some time, and social opinion can change quickly when people see new developments.

morkalork · 1h ago
That's part of why the trojan horse works so well, what is an unacceptable risk for someone healthy can easily be acceptable for someone with an otherwise untreatable condition. Then by the experience and knowledge gained, it becomes less risky for everyone.

I think part of the problem is that “really good” and “really bad” are not universally accepted norms for any given ethical question. What you’re seeing is your own value system assumptions being checked.

It’s perfectly reasonable to say that while a technology has the propensity to be used for evil, it also has positive applications and that the real benefit now outweighs the potential downside in a hypothetical future.

Otherwise you will go down a rabbit hole at the bottom of which lies a future where we all just kinda dig in the dirt with our hands until we die because every technological innovation can be used in a variety of ways.

Like, it’s silly to me that I can’t bring a 1.5” blade keychain utility knife on a flight, and then they hand me a metal butter knife in first class. I could do way more damage with that. But they allow the butter knife because the utility has shown to far outweigh the potential downside that hasn’t manifested.

>This is one of those things that is easy to say precisely due to the impossibility of it ever actually becoming a real decision you have to make.

It's true. But things like this should be easy to say right? Like we may not be able to act logically. But we should be able to think logically, communicate logically and show that we are aware of what is logical.

My post got flagged meaning a lot of people can't separate the two things. So for example I may not be able to kill the baby in reality, but I can at least see how irrational I am.

The person who flagged me likely not only can't kill the baby. He has to construct an artificial reality to justify why he can't kill the baby and why his decision must be rational.

A baby Hitler gaurantees a future with a grown up Hitler. Killing the baby eliminates that future.

There could be other babies that can also grow up to be future Hitlers. So let's say 4 such babies exist. By killing one I eliminated 1/4 for futures with Grown up Hitlers that exist.

This whole thread is getting flagged. Likely by an irrational parent who can't even compute natural selection, babe, and Hitler all in a single paragraph.

Heck, if parents could provide a trust fund for their kids in a way that their kids couldn't piss it away, they'd be all over it. (I'm sure this exists to varying degrees.)

Look at what wealthy parents already do to get their kids into colleges or out of jail. I think it's ridiculously naive to think that we parents wouldn't jump at the chance to write generational wealth into our kids' genes.

(This is not an argument that developing this capability is a bad thing and should be stopped.)
