AI music appears to be reasonable music, but it carries no human emotion, it has no intent to exist and stand up on its own.
That's key to explain when it comes to writing or anything. AI assisted anything, sure, maybe, but AI for creative purposes is bland and ultimately poisons the well.
No one really wants to go see an AI movie at the cinema, except maybe to say that I tried an AI movie as a novelty item, like scented movie screening.
