It’s also worth noting that projects are rarely contained within the bounds of a programming language. If you’re building a web app, what’re language you use will still come down to HTML/css. You’ll also probably be using SQL, which is also unlikely to change. But there’s the other side to that. If you’re graphics programming, OpenGL provides the same features regardless of language. The OS APIs are broadly the same - the steps to set up a TCP listener don’t change with the language. The APIs for all these may be subtlety different between languages, but not significantly. It’s a case of translation rather than relearning, and although I can’t speak for anyone else I find that translation quite painless.
