I'd like to chime in the point out that the vast majority of employed artists aren't making anything as creative as cover art for a hobbyist board game. If they're lucky, they're doing illustrations for Barbie Monopoly or working on some other uncreative cash grab. More likely, they're doing incredibly bland corporate graphic design. And if you ask me, the less of humanity's time we dedicate to bullshit like that, the better.
Professionals will spend more of their time concerned with higher order functions like composition and direction. More indies and small businesses will be empowered to create things without the added expense. And consumers will be able to afford more stuff with higher quality visuals.
That's anybody, really. Everything you've ever accomplished has depended upon the insights and knowledge of countless other people who never saw a dime from you for it. That's part of living in a society and it's a crucial part of how it advances.
I think that most of the value we get from creativity isn't from the mechanics of creating something. And I think that by removing the mechanical barrier, we unlock that value much more widely across humanity. Art is a form of communication. Will we ever feel the same connection when that communication comes wholesale from an AI? I don't know. But we're certainly not there yet.
