ссылку сюда ещё не приносили? Торвальдс высказался по возможному использованию Rust в ядре Linux — правда, у него осторожный взгляд, не холиварный:
"I'm interested in the project, but I think it's driven by people who are very excited about Rust, and I want to see how it actually then ends up working in practice. Personally, I'm open to it considering the promised advantages and avoiding some safety pitfalls, but I also know that sometimes promises don't pan out.
Rust's primary first target seems to be drivers, simply because that's where you find just a lot of different possible targets, and you have these individual parts of the kernel that are fairly small and independent. That may not be a very interesting target to some people, but it's the obvious one."
