Why do you want sophisticated code ? That word seems out of place from the other two to me.

Rust doesn’t introduce the same problems as C, but it sure does introduce a lot of other problems in making code overly complicated. Lifetimes and async are both leaky abstractions (and don’t even work as advertised, as rust-cve recently demonstrated), macros can hide control flow…

C is unsafe, sure, but also doesn’t pretend to be safe. C is also stupid simple, and that’s a good thing : you can’t just slap ArcMutexes around, because by the time you know how to code them yourself you also know why you shouldn’t do that.

I hope Rust can reach a point where its safety model can be formally proven, and we have a formal specification and a stable ABI so we don’t have to hard-compile every crate into the binary.

But I personally expect something with some of Rust’s ideas, but cleaned up, to do that instead. Actually, I wouldn’t be surprised if C itself ends up absorbing some of Rust’s core ideas in an upcoming standard.
