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 explored something similar this weekend. Basically kids ask questions and are curious. They like to be read to. Use chatGPT to write an original short story and enable the parent or kid to either extend the story back or forward in time or expand on a particular character or sub plot. V interesting potential there!
