When you really think about it, one of the fundamental flaws with AI is that it literally cannot create anything new because it requires training data that already exists. The best it can realistically do is mix and match traits of other animals until it creates something "new." If Star Wars was made today and entirely with AI it would not have the necessary training data to make anything even remotely close to what we got back in the 70s and would look like... This.
And this is a huge problem with pretty much all "AI" today. We say that they can "learn" and be "trained" but it's basically just large and incoherent database that recycles the data in a way that makes sense to humans. It's like if you were tasked with creating concept art for a movie or a game but your boss said you can't start with a blank image and can only modify existing concept art. We already see copy/paste movies, games, and books all the time and we already don't like it.
