I do think purely AI art isn't really close to disrupting anything since what is being produced without human editing/selection is generally pretty mediocre, as the copy writer in the article mentioned, and we are quite sensitive to the quality of the entertainment we consume, unlike marketing copy.
Computers are way better than humans at lots of things, but that doesn't stop humans from spending lots of time on many of those things they enjoy even though a computer can do it better.
Like playing chess just for one example.
I do creative stuff because I enjoy doing it. I couldn't care less that a computer is better than me at it. Lots of people are better than me at it and have always been. Just as that doesn't stop my own enjoyment of doing it myself, neither would a computer being better than me stop my own enjoyment of it.
The point is, you won’t know
I want to go listen to a real live person perform.
Same for all the other performing arts for that matter.
I think we are really far away from robots controlled by AI performing a live Broadway musical for example.
Heck we are far away from robots singing with the human emotion of a talented singer as far as I have seen.
