I think you are mixing up art with reproduction. Sure most stuff being produced out there by humans are simple variations of known themes and storylines. Too often mediocre at best.

But AI is 100% dependent for her hard data input on original content producers. Aka people. People with unique real-life experiences, like the French aristocrat, writer, and military aviator Antoine de Saint-Exupéry...(The Little Prince), Andrei Tarkovsky and Stanislaw Lem (Solaris), Peter Greenaway, etc.

The keyword here is the translation of "unique set of real-life experiences" into original content. There is a very physical and historical dimension to these real-life experiences which I don't see AI ever be able to grasp. Antoine sitting in his crashed plane in the desert, Andrei and Stanislaw living under communist repression, etc.

So yes, no more room for people on the reproduction line (second-hand industry). But isn't that really good news? No more bullsh** jobs, freeing up lots of time to go for unique real-life experiences:) Aka to live a life.
