I don't have a link or reference handy but your question reminded me of an old cybernetic device that improvised music along with human musicians. It could detect and respond to novelty in the human music, and it would get "bored" so to play along with it the humans had to figure out novel musical, uh, stuff... melodies and whatnot. There seems like a vast difference between music and D&D stories/games, but just yesterday there was that RNN-sci-fi-editor experiment on here ( https://news.ycombinator.com/item?id=22427958 https://news.ycombinator.com/item?id=22427958 ) so maybe it's not as far-fetched? In any event, being a good DM is really really fun, I don't think I'd want to let a computer muscle in on it, eh?
