Yeah, same boat. I'm continuously learning new shit with C# and I'm starting to understand Angular after all these years. I could switch back to Java with few issues.

I would love to learn Rust, but there's no time right now.

Exactly this. It's often about finding the right balance between technically optimal, and socially feasible (lacking the right phrase here).

The nerds brimming with technical expertise often neglect the second point.

Oh - wow! I was about to complain about how https://join-lemmy.org/ is a shining bad example in this regard, talking about server stuff right away and hiding how Lemmy actually looks until page 3, but apparently they changed that and improved it drastically. Cool, good job!

Anyways.

For collaborative projects especially, it is important to strike a balance between tech and social aspects. Making poor tech choices will put people off. But making your project less accessible will also result in less people joining. It's crucial to find a good balance here. For many coming from the tech side, this usually means making far more concessions to the social side than intuitively feels right.

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.
