I can almost see your point, but there are two big problems:
1) To date, there has been no example of AI that is good. It's not even close.
And 2) Why should I be interested in a story nobody was interested in telling? If you don't want to make a video, or tell a story, or write a song, then...just don't. Why even have an AI do it?
what if you write the story yourself, and use AI only to visualize it?
"1) To date, there has been no example of AI that is good. It's not even close."
It's because you haven't noticed. It's an observability bias.
