Last year saw a proliferation of talks and articles about safety in C++. Lucian Radu Teodorescu gives an overview of these and presents a unified perspective on safety.
But I still agree with your premise that performance isn’t the deciding factor. Which means that other than legacy reasons, C (and C++) really doesn’t have much going for it anymore.
I think you’re expressing uninformed and uneducated opinions.
Even Debian’s computer language benchmarks game showcases C consistently outperforming Rust, with some notable exceptions in some key benchmarks.
And Rust was not a thing 40 years ago.
Anyway, I think I proved my point with regards to the silly idea that performance is a decisive trait. You cannot have your cake and eat it, too.
Nah, 40 years ago this discussion already existed and it was between C and FORTRAN at the time. FORTRAN was often faster than C, precisely because of aliasing rules that Rust now benefits from as well: https://stackoverflow.com/questions/146159/is-fortran-easier-to-optimize-than-c-for-heavy-calculations
Btw, are these the Debian benchmarks you were referring to? Because I can see C and Rust trading blows with one another, but neither taking a consistent lead. Nothing that points to an undisputed performance lead surely. https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/rust-gcc.html
