It almost never makes everything correct from the first try.
All these song generators, video generators, etc.
People are regenerating and regenerating, which takes hours and maybe days, until they get the okayish result. Then they share it and everybody else thinks that AI is like this everytime, but they don't see "behind the scenes", how much time was spent.
When I hear AI songs I get first positive impression of how well it sounds, but it still nowhere near when I start re-listening to it, learning lyrics, whistling it afterwards, as it is with real songs. Because it's a mastered mediocrity. Do you like mediocrity? Films, that get 4/10 on imdb (except some misunderstood ones or ones that get low rates because they go against current political agenda).
