One thing you can say for 2001 is that it wasn't a copy of anything else. In fact it invented a lot of the visual tropes that are still used in science fiction movies.
That's not a thing that happens much now. There were some genius-level directors around in Kubrick's time, but now virtually all movies look like they live in the same CGI world, with standard stock characters, and similar directing tropes.
It would be huge fun it CGI stopped working for a few years, and directors had to go back to telling stories without it.
Music feel the same. After the 70s most things have been done. 80s brought some pop color and craziness to it. And now what is there to invent ? hard to say.
Maybe we hit the ceiling, maybe there's still room for surprise ..
Maybe it's a transitional period where people are believers of more K (4K 8K... ) makes better movies. I think not. It's like music, it's a balance. Maybe later the industry will get bored by chasing new features and moviemakers will go back to making better movies, not better photos.
