I think this boils down to a desire for connection, rather than creation, and is part of a decade-long consumer shift toward seeking individual relationships and bucking corporate brands. TikTok, Twitch and YouTube are the primary channels for this, and it's on display 24/7. There are millions of people throwing mountains of money at individuals, not just for sharing their thoughts or talents, but by creating a genuine connection and community around that content. And that's the reason humans won't stop creating content no matter how great AI gets -- because it was never really about the content to begin with.
However, AI will assuredly become the dominant form of entertainment at some point, as the predictive capabilities alone would allow for flawless content suggestion for any given situation. And that's before the inevitability of generating content indistinguishable from anything Hollywood or Nashville can produce, including online personalities that mimic human behavior well enough to create the same "genuine" connections I mentioned in the first paragraph.
