I’m perfectly comfortable with C, it’s a neat, small, language. I actually understand the whole of the semantics (at least the POSIX ones). I also happen to speak x86 assembly quite fluently (as long as it’s not SIMD noone speaks that fluently, last time I actually wrote assembly in earnest x87 was still relevant). The thing is though I’m more comfortable with Rust, even if I don’t understand absolutely everything: Because it’s less mental load. I don’t need to worry about so many things at once, don’t have to keep a thousand assumptions in mind that that pieces of code I’m not currently working on are making.

No, driving a unicycle instead of the metro doesn’t make you a better commuter. It makes you a better unicycle driver.
