Rust productivity at your company?

This is a part two about the post I recently made of Rust vs competition.

If you're using Rust at your company, how's productivity? Especially with onboarding new devs, and larger codebases?

Do you use any other not-as-complex languages (JS, Go, etc)? If so, how's the productivity of Rust vs those languages?

I'm especially interested in whether Rust could be a good fit even for non-critical like CRUD web backends, indie game dev, internal tooling, etc
