Frankly I don't think one even needs to learn it, if you know a bunch of other languages and the codebase is good. I was able to just make a useful change to an open source project by just doing it, without having written any lines of Go before. Granted the MR needed some revisions.

Rust is my favorite, though. There are values beyond ease of contribution. I can't replicate the experience with a Rust project anymore, but I suspect it would have been tougher.
