Ask HN: Why do/don't you use C?

I've been having a blast writing projects in C lately (emulator, raycaster) and using it extensively for a game engine I'm making.

But I always hear people saying "just use Rust or Zig" - but C is actually a great time, and I'm happy the naysayers didn't put me off.

So, do you, or do you not use C?

If so: why, and what for?

If not: why not, and what do you use instead?
