Not that I doubt that one day people will simply gather around the AI infinite story creation bot. They just won't know what they're missing. :(
More seriously, the novel is a unidirectional medium of communication. Not a relationship. That said, it is meant to convey a perspective. I don't care if it's a human, a robot, or a little green man's perspective. It just has to be an interesting, useful, or enlightening perspective that I didn't already share.
Right now LLM's don't really have unique perspectives, that may change. So I withhold judgement. As of today, I wouldn't read an LLM's novel. In 10 years, who knows?
> The value comes from the simple relationship between the text and the reader
This is not some universal truth, yet you state it as such.
People can get different things from a text.
