about the second part of your answer; my (probably very rare) opinion is that our job is not to "work in erlang" or "work in rust", is "solve problems/automate stuff". If I ask you to work in Foo instead of Erlang, it's the same job. I highly doubt that your job is slow because Go and fast because Rust, it's slow because process/idiots in other teams/idiots in your team/idiots as your "agile coach" etc.
I understand wanting to have a good career, but language is never the obstacle to a successful career. Also, this implicit bias that people who know exotic languages are better is completely false.
