Rust could have been a great systems programming language. Unfortunately, it has been taken over by web developers. All systems programming jobs are still in C/C++.
It could have been different if Mozilla hadn't rewritten all of Firefox in Rust while complaining about C++. Firefox dropped from 10% of the web to 3% and into irrelevance during that Rust rewrite and gained nothing. Ironically, Chrome is written in C++ and ate their lunch from Firefox's plate.
You better go tell https://github.com/oxidecomputer/hubris to pack it up because they can't realistically continue to write their kernel in Rust and that Rust is for web developers now.
