Photography is capturing something real in the physical world. Even if the action can be boiled down to “push a button” the photographer needs to have at least some presence where the real event is taking place.

AI art is not a depiction of a real event and requires no physical presence. It’s also not being brought to life by the person taking credit for it. That’s not to say AI generated images can’t be cool or useful but I don’t think they are art. If your definition of art is loose enough to apply to AI generated images then the I think the artist credit should belong to the AI itself or the team that wrote the software, not the person typing in prompts.
