I'm no Rust expert, but in my experience the borrow checker is a pain for a bit, then you start to get a sense of what works and what doesn't, and after a while it has taught you to write cleaner code.

"Karen compiler" is almost perfect, except unlike Karens, the compiler is delightfully helpful with the error messages it gives you (usually). It usually gives a straightforward error, an error code, and sometimes, an easy fix.

As someone that started with Rust, but just yesterday had to fix some C++ code, working with any other compiled language makes me shudder. I have nothing but respect for devs that have to wade through stuff like that.

At least it has something to complain about, unlike Karens.

Ha, I'll steal that! "Karen compiler" - quite fitting, to be honest.
