Cryptobubble definitely had a part in subsidizing early expansion of Rust's crate ecosystem and first jobs, but I think at this point Rust has grown and matured so much that it's not dependent on any single thing.

I know Cloudflare is depending heavily on Rust in its services. AWS is invested too. It's used at Dropbox, ByteDance, Canonical. It has already made its way into being part of infrastructure in many companies, and there aren't many alternatives for it, so there's momentum to keep it going.

Even in this sample of explicitly Rust-specific jobs that "most" is already close to a half, and the sample isn't including jobs that use Rust alongside other languages (which in my experience is common, since Rust is good for libraries/plug-ins/components/low-level utilities).

That would be really sad, I’m not sure why you would say something like that. You can express dislike about (part of) the rust community but why would you wish Rust to lose traction? Even if you don’t like or care about the language it is a fantastic addition to the world of programming languages (even just from a research/academic/intellectual point of view), and push for a healthy competition in the world of system programming, something that benefits all of us.

Pretty unlikely since Rust isn't a bubble and it's used in way more places than just crypto. Those places just don't advertise heavily on jobs boards.

It's probably not likely at all. While Rust's correctness guarantees through ownership checking can be approximated by other programming languages through garbage collectors, it is not a widely understood fact that Rust mutability checking is also a great tool for multi-threaded programming, very challenging to get right even by veteran programmers. On top of that, Rust not only features syntax that's quite modern and ergonomic (analogous to Swift) with elements of functional programming, but Rust also offers modern abstraction-based programming constructs through traits (analogous to Swift Protocol-Oriented Programming). Even the ever C-advocating Linus Torvalds has already agreed to allow Rust as a second language within the Linux kernel. IMHO, Rust is not just a bubble - it will probably only keep growing in popularity.

I don’t see this happening. If you know rust you can use it elsewhere.
