So, before the invention of the camera, the most valuable and most popular creative skill was replicating people on canvas as realistically as possible. Yes, we remember famous exceptions like Picasso, but by sheer number of paintings the most common were portraits of rich people.

After the cameras took that job away, prevailing art changed to become more abstract and "creative". But that still pissed off a lot of people that had spent a very long time honing a skill that was now no longer in demand.

What we're seeing is a similar shift. I think future generations of artists will value color theory, composition, etc. over specific brush stroke techniques. AI will make art much more accessible once enough time has passed for AI assisted art to be considered art. Make no mistake: it will always be people that actually create the art - AI will just reduce/remove the grunt work so they can focus more on creativity.

Now, whether billion dollar corporations deserve to exploit the labor of millions of people is a whole separate conversation, but tl;dr: they don't, but they're going to because there is little to stop them in correct economic/governance models.
