I'm willing to work on replacing most GNU / UNIX tools with Rust equivalents. Anyone willing to fund such an effort?

Seriously though, as others are saying sarcastically, I'll join them right up: "C is completely fine, you are just doing it wrong, it's a safe language when you know what you are doing".

Yeah, about that.

It's not a matter of "if", guys. It's only a matter of "when".
