Can't speak for why Zig doesn't have a problem but Rust is cursed by its success: it lowers the barrier for improvement enough to entice you to always improve it.
And you just keep refactoring/improving/desperately trying different ideas, because it never feels right.
It's ok if you don't agree but pls don't try to make my responses look like I like Rust, I don't and I'd happily get those years back if it was possible.
