Hollywood will have to reinvent itself or will become marginal. Actors will be licensing their 3d models and do voice-overs in the beginning (after that even voice will be transferable), but gradually it will be more influencers/celebrities.

Imagine if "AI" would generate beautiful movie/tv show from reading given book series, with maybe minimal edits required to keep pace as expected, probably several versions with various trims for die hard fans as much as casual viewers.

No fan complaints about twisting original book into mess. Imagine things like Wheel of time, Malazan book of the fallen or Hyperion cantos done exactly as you read them, no 'creative' invented crap that somebody felt urge should be added just to increase views.

This all will be for old schoolers like us. What young will be doing on next generation of tiktok is anybody's guess.

Another example would be properly self-adjusting and generating games tailored to individuals, virtual world reacting to actions, be it singleplayer or mmo.
