That trailer was souless and dull. AI is far too limited as it is constrained by what has gone before and the current meme. That means it is limited to knocking out populist tropes which it will believe will please the most people. As a result it will fail in the same way as everyone else in the past who has tried to do the same has failed. People kick against the jams, especially true with emerging generations, whilst the current brood of AIs aim to please. It's the equivalent of having your grandpa DJing at rebellious party you had when you were 16.
