I think for this reason human artists won’t be replaced anytime soon. The human brain is insanely efficient. I have a theory that humans are smart not because of some magic algorithm in the brain, but more because we process so much input we can recognize so many patterns at once.
IIRC we‘ve build a super-computer with as much “processing power” as a human brain (although we also don’t know exactly how neurons work). But it’s not just that. We have to build that computer, run it for decades on all kinds of input, and then we have something as smart and creative as one human. Not necessarily even an artistic one either. Meanwhile there are over 7 billion humans, plenty of whom can make art for cheap. And that’s why we’re far from companies using AI to make their graphics.
I’d love to see AI stories and art, but until we get much more processing power i doubt we’ll get AI making novel creations. These abstract art pieces? Sure. Transferring styles (e.g. Van Gogh, water color, polygonal) between paintings? Sure. In fact I bet most artists will be using AI-augmented tools. But for a long time AI will still involve human work and/or be relegated to different styles.
