I think most of this stems from the fact you can focus on the problem you want to solve, instead of mundane plumbing (like in C or C++ project).

Suuuure, some people will complain about the borrow checker, but I think it's people who are mostly inexperienced with Rust. It's not really an issue for anyone after they've played with the language for a while.

Like, these days I rarely have to debug a borrowing errors, and if I do it's a few minutes of work tops.
