It's very widely used, that's for sure. But it's increasingly not a good choice - in the examples you give - web, ML, GUIs, it is not first class in any of those (and not near to it in the latter two).

What's next for Java should be relatively little change; let a language like Kotlin without all the baggage be the way ahead on the JVM. There's a remarkably good compatibility story there; way better than basically any other language ecosystem out there, that's the real legacy of Java.

I like to think of Java as 'a reasonable choice for almost any problem'. Almost never the best one. If you're looking for a single language to standardize on for all the things corporate-wide, it makes sense. But don't lie to yourself thinking you've picked the best tool for any job.
