Van Gogh invented Starry Night without any prompting despite it not being a real scene (much less anything he had ever seen and such abstraction was very rare in the 1880s). Picasso made Les Demoiselles d’Avignon in 1907; it was so radical even his fellow artists were unable to comprehend it.
It doesn't change the fact that DALL-E is pretty amazing tech, but it's still as far behind human ability as any AI is today. It is way way better than what came before, but that's true of most technologies.
It's just like Dada poets did 100 years ago: you use a mechanical process to generate quasi-random output, and then you choose some of this output to present to other humans. The way you provide input to the mechanical process (e.g. what words you choose to put in the hat) and the curation are the real creative part of the art, not the mechanical process generating the text itself.
