Assume an LLM trained on your favorite writer / fiction series was indistinguishable from the original. Would you spend time reading infinite content in that literary universe?

i.e. The Foundation or Dune but the ability to zip backward or forward in the timeline

I want to read the backstories of various universes of my fav sci-fi novels and generated storylines of different characters

Or generate visual universes - that might be more interesting! Just reading it is tiring. I don't like LLMs currently can build out these worlds though. Maybe in a hypothetical future
