You didn’t say that explicitly, but that’s the implication of the world you’re imagining. You’re literally describing the death of all forms of creative industry–human musicians, human writers, human actors–all replaced with AI. You’re describing the death of shared creative experiences; with an audience of one, nobody commiserates together over a movie they watched, or a book series they discovered, or talks about the new season of a favorite TV show together. You’re describing the death of any form of subversive thought; with all media produced by AI, guard rails on creativity are trivial to introduce, gently redirecting, or outright prohibiting subject matter that is deemed inappropriate (and if you think I’m wrong, just imagine the world you’re describing in modern day China–do you seriously think they would allow AI to proliferate that allowed you to create a movie about Tianenmen Square?).

The world you’re describing sounds like a plastic, lifeless, lonely hellhole. It’s the kind of world sci-fi authors would use as a dystopian background.
