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.
I admit to not knowing how running an open source project goes, but wanting more contributors seems like the wrong metric compared to better contributors.
I understand the pitfalls of C are not limited to segmentation faults, but I suspect it would be more productive to fix C by including some of Rust’s better ideas than to throw it away, as seems to be the current trend.
I don’t think Rust is wholly bad, to be clear, but it seems over-engineered to me, and the fact its useful new features don’t even completely work (see rust-cve) isn’t very encouraging.
I would recommend listening to Jonathan Blow’s opinion on Rust, which I tend to agree with. I personally think I’m just going to stick with C until Rust either becomes the standard, or I retire and let the next generation worry about that.
