if that works for you go for it, AI works best with constraints IMO, with the downside that it can slow development. i suspect it would lead to buggier code if you let it go ham wild on C code.

Buggier code is just lack of harness these days.. It seems to me that if the code is small, unix-style, then Claude can pretty much code C without any memory safety issues. Rust was created for humans. I am not sure the limitations of the language are worth the cost anymore.
