I think what OP was drawing a comparison to is that AI right now could not come up with an award winning novel from the spark of some creative notion and working up from there, as opposed to just mashing together what has already been done and calling it a day.
I agree, but in this field we value evidence. So there needs to be some test of novel-writing abilities.
Once there is, AI companies will be out to score highly on it.
Wait for a resurgence of Philip K Dick-style novels as humans desperately try to write things LLMs cannot.
I myself can't wait for Finnegan's Wake 2
