To put it one way, some mine blocks as art, some carve sculptures as art. Some build walls as art, some build buildings as art.
The ones building buildings and carving statues want machines to do the work of gathering the resources. Those who make games and movies want graphics and audio.
To the pixel artists, getting their drawing in a game is part of the art, but to the game dev, working with a pixel artist may be a chore.
We'll see a lot of reshifting of these forms of art - the pixel artist will be able to use AI to make games or variations and such, and may find art in becoming an art director instead.
