Here's my thoughts from Twitter a while back and judging by the comments I'm reading, hopefully they'll be valuable/interesting here too:
From an "art" perspective DALL-E, Imagen, Midjourney bring little if anything new to the table...Not to say they aren't incredible, but "making art with words" has been well-explored for a century: Duchamp's "Unhappy Ready-made" in 1919 is one example, Moholy-Nagy's "Telephone Picture" https://www.moma.org/collection/works/147626 is another. Indeed are these AIs any different from conceptual artists outsourcing their work to other humans? I don't think so. What I _am_ seeing from various conversations, though, is that they are game-changers when it comes to inspiring people to create, and to read and think about art history and philosophy. And that has to be a good thing.
