I expect a bigger corp with a sustainable business model will scoop it up. Rust is too promising to die at this point.

I hope so, I bet on Rust for my latest venture. I'd be so sad to have to rewrite it in C++ down the road.

  Probably start now. C++20 is a much more fun language than C++11 was, which was itself overwhelmingly more fun than C++98 or C. C++23 and C++26 will continue the trend. If you are not constrained to shoehorn yourself into a C or C++98 environment, all the memory-safety worries Rust was supposed to help with fall away.

Is it though? Most of it seems to be hype. It’s great that programming languages get researched and improved, but do they actually improve? How is improvement measured?

    I've studied and followed Rust since before 1.0. I have no doubt that it lives up to its technical promises. What I'm more skeptical about is whether living up to those promises yields a tangible benefit. By skeptical I don't mean to imply that using Rust doesn't yield benefits, just that I would like the PL research world to be in a place where questions like this can be solved properly.

  I don't think calling it mostly hype is anywhere near reasonable. It's a mature language with a large ecosystem in use by a variety of companies.

    In ten years it will be mature, if anyone still uses it. If not, it will be because people who like Rust today are off chasing some new hotness. Whatever the direct technical impact of the layoffs, the language's credibility has taken a huge blow. Its future was already uncertain, and is, being honest with ourselves, substantially moreso now. There is a lot to like about Rust. I hope something survives. A sequel--Dust?--could keep its strengths but focus at the outset on fast builds and better visibility into dependencies, to avoid NPM disease. There must be lots of ideas that it seemed too late for. Maybe make it relatively easy to import old Rust code, to help get jumpstarted? Rust's real reason to exist, to displace C, was not working, and may have been doomed from the outset. Rust has been taking users from Java, Go, and Python; and some C++, in places where coding has been hamstrung by archaic "style" restrictions. But very few C coders have moved. That may be just because any who might have jumped already had. (Some of those might have come over from a pause at Go.) Rust is a far, far better language than Java and Go. It never had a chance against C++, which picks up more new users every single week than the total who have ever used Rust. If Rust or its sequel could give people on Java and Go a language with a future, that would be a seriously worthwhile achievement. Making a borrow checker less strident would aid adoption; so you always know whether your code and each dependency are "clean", without being prevented from getting work done. The recent experience with that very fast GUI library with a few too many "unsafe" bits made a very deep impression. Nobody wants that experience, especially starting out. Code that is not borrow-clean would get clean soon enough if it is used; and, frankly, dead code never needs to be clean.

      What grounds do you have for saying it's not a mature language? It's more than 10 years old. Subjectively I would feel as confident in safety and feature set as any other mainstream programming language. I also strongly disagree that Rust has any sort of an uncertain future. It appears to be a well run and stable project. Regularly putting out releases from a variety of contributors.

  It doesn't sound like you've learned and used it.
