I mean I don't hold that ai can't be used to make something really beautiful but it's most often used as a lazy way for non creative people to make art, and that is rather lazy.
It says something about the work ethic of the development team and if you put it a demo, which is supposed to get people into your game and have it have zero percent gameplay and fill of 'placeholder' ai art there's something fundamentally stupid going on, of which the ai is more a symptom than the cause.
