Once you know a few languages and the principles for how a computer works moving to a new one is easy. Don't think of it as being a "Java developer", but a programmer. It's just a tool.
We did not learn languages at uni, but concepts. You use the same data structures and algorithms.
I think you'd be surprised, try picking up rust for some advent of code challenges. If you know Java Streams and C/C++ lower level programming all that you're missing is some pattern matching.
The very start of Israel in 1948 was Israeli militias (one fascist militia with a line of continuity to the current pm) driving out hundreds of thousands of Palestinians from their homes, forcefully and with a few slaughtered villages to set an example.

We'll get something like language servers but for AI eventually.
