They certainly are! Especially when money is on the line, and the best musicians, actors, and artists are extremely well compensated making their positions extraordinarily competitive.

Sure, but I think you neglect to consider the defeating feeling it would bring to dedicate your entire life to mastery of a subject only to be completely and utterly, hopelessly outclassed. Almost every such person is already hopelessly outclassed by someone in their field, but those people are so rare that they have tremendous exclusivity surrounding them. Compare that to the scenario of having any 12 year old with a smart phone being able to instantly produce a totally novel and dominate piece of artistic expression developed by an algorithm on their phone. Then recognize that in a world with that level of AI sophistication, there'd be very little of value that a human can even offer other humans at that point. It would be... not great to the psyche, economy, or society.
