Would Skyrim be better if you could talk to ever guard about what they had for breakfast? Would you ever be able to shake the knowledge that it's just an LLM pretending?
I'm not sure how best to put this. I think for me at least, I get the most enjoyment out of discovering my way through a story that somebody else wrote. This is maybe why I don't like multiplayer games as much a single player experiences. I want another human to tell me a story, and I love the feeling of uncovering the little pieces of story and wondering if I've got it all and how much more there is. If an LLM is just randomly making it up as it goes, I'm not discovering anything. I'm not hearing a story. Instead, I'm just having a transient conversation with myself.
I guess it's equivalent to the difference between visiting an art gallery, versus watching a computer generate fake paintings. One has human intent behind it and that makes it compelling, the other is soulless and empty
