I wrote a small app in REBOL once, just too automate some stuff for some managers in a job about 20 years ago. It's quite nice, but I don't think I'd want to write anything significant with it.

I used it once to build a simple web scraper and image downloader, and it worked really great for that. It was right in the wheelhouse for the language. (That was REBOL, not RED, and many years ago.) Honestly I'd just do it in Python, now, even though it's not as interesting.

"In 1988, Sassenrath left Silicon Valley for the mountains of Ukiah valley, 2 hours north of San Francisco. From there he founded multimedia technology companies such as Pantaray, American Multimedia, and VideoStream. He also implemented the Logo programming language for the Amiga, managed the software OS development for CDTV, one of the first CD-ROM TV set-top boxes, and wrote the OS for Viscorp Ed, one of the first Internet TV set-top boxes."
What a legend!

Right? And I think that's what keeps bringing me back to REBOL, and thus Red. They don't appeal to me on the face of them. Like, the code examples look interesting but in a "magical" kind of way that strikes a little bit of fear into my engineering heart. But with that kind of pedigree, I can't dismiss the ideas. If Sassenrath came up with it, I bet there's a kernel of awesomeness inside.

I figured they were cooked when they started doing weird cryptocurrency-related stuff. I really hope they get to their 1.0 release someday.

Same. I was regularly following it until they started talking about an ICO and began focusing too much on making a dialect for block chain stuff.
The idea between having the red system language, regular scripting language, cross platform gui, and native executables was really cool though. I remember being interested back in ~2015, so my question is...what's going on as it's been a decade. I know the project is crazy ambitious of course, but how close are we to where this is at a stage where most would consider it production worthy.

IIRC think their original roadmap had 1.0 around 2020. And that was going to include everything, including async written from scratch in a language where nothing was made for async.
Then the roadmap slipped, and then never mentioned again.
But I haven't looked at the language or discussions around it for a long while now.
The website looks like 2013 and much of the content is as well. There's a GitHub repo that I couldn't find from the website: https://github.com/red/red

The repo seems to be alive and kicking.

This is like the only programming language I could never learn. I just don't understand anything and I can't build any mental model of what's going on behind the hood

I wrote a paper on REBOL back in college. It is very interesting, but the syntax is definitely weird. You might think of the function call syntax as being sort of Forth-like, but with the tokens in reverse order. So like a Lisp, but without required parentheses. e.g. in the example
send friend@rebol.com read http://www.cnn.com
`read` knows that it takes one argument, and `send` knows that it takes two, so this ends up being grouped like
(send friend@rebol.com (read http://www.cnn.com))
(which I think is valid syntax; that AST node is called a 'paren').
Weirdly, the language also has some infix operators, which seem a bit out-of-place to me. I have no idea how the 'parser'[1] works.
[1] 'parsing' happens so late that it feels funny to call it that. The thing that knows how to treat an array as a representation of an evaluatable expression and evaluate it.

it's lisp with square braces instead of parens (and then a whole bunch of other random things like a gui library in the standard library?)

It's actually more like Logo, which is Lisp with square brackets instead of parens and fixed arity.
Sassenrath wrote Amiga Logo before starting REBOL.

The square brackets aren't really analogous to Lisp's parentheses; REBOL / RED use parentheses for the same purpose, if you need them. The square brackets are more like square brackets in Factor or Joy; they are 'quotations' around a list of words (or other syntactic structures; basically they make a list that is not evaluated immediately).

I haven’t looked at this in detail, but it seems they confuse “human-friendly syntax” with “absence of (<[{“.
I've looked it a few times over the years. It's neat. I've never written a single line of it, though.

Edit: found some old discussion here. In 2018 they were at version 0.6.4 https://news.ycombinator.com/item?id=18864840
In 2025 they are at version 0.6.6: https://github.com/red/red/releases
