Yes Java is uqititous and it's not going away for 30 years at least. See Cobol. Java also has had significant improvements in the language so that there is less incentive to use other JVM languages like kotlin and it's fully interoperable with heartland code bases as far as I know

The number of flaws that make Java inferior to other JVM languages is surprisingly small. By far the worst parts are excessively verbose "Beans", nullpointer by default, the JEE ecosystem (there are good alternatives) and the high RAM consumption (a JVM flaw). Honestly 80% of the value I derive from using a different JVM language come from avoiding NPEs, getters and setters. The remaining 20% can be very useful but they are certainly not essential nor can they be considered mandatory.

Whenever possible, yes.

Sane language. Fantastic tooling. Huge ecosystem. Backwards and forwards compatible like few other things.

> People are still using Java?

Yes, pretty much the whole world is using Java. Some FAANGs use it as basically their default software stack, and at most have introduced some Kotlin along the way.

The world doesn't revolve around flavor of the month tech stacks.
