This might be controversial, but "Safety" and "Speed", in the same ecosystem, are not free. The cost is heavy syntax and heavy cognitive climbs. Why Rust was ever sold as a language for the masses is beyond me. A safe, fast, hard language is something you use for operating systems, aircraft, etc.

I adore Rust because it does all the things I remember being told to do in C, but without me remembering to do them: Error codes from all functions, Ownership models, etc. But those are not good reasons for me to use it for anything I wouldn't use C for.
