Thanks, that's reasonable to say, much more reasonable than "Rust is the one true language that is right for everything". No idea about long term careers in anything related to programming, because of AI displacing every sort of knowledge work. But Rust will probably stay relevant for a while.

Certainly, the concept of building a career around a programming language has always been unsound. Good programmers know lots of languages and can pick up new ones as the need arises.

If you want to study one language as a means of absorbing new ideas, I'd suggest Haskell rather than Rust. You probably won't get to use it at work directly, but it will make you a better programmer in general. learnyouahaskell.com is a good place to start.

The stuff here is way more professionally important than being good at Rust or any other language: https://antirez.com/news/112
