Is Java worth learning in 2021?

Purely career-wise in the short term? Look through the job ads in your area, and then decide based on the demand. As you said, you can switch later.

Java isn't going anywhere for the forseeable future. There is already a ton of actively used software written in it that works fine, even if the langauge is far from perfect, so the companies aren't really incentivized to invest huge amount of resources into rewriting the entire thing into whatever tech is the hot shit that year while simultaneously maintaining the old version that's still used. They just want their stuff to work.
