Maybe we're just search engines of a similar kind.
An additional aspect of human art is that it (usually) takes time to make. The artist might spend many hours creating and reflecting and creating some more. The artist's engagement with the work makes its way into the final product, and that makes human art richer. Could future Dall-E version create sketches and iterations of a work; is there a limit to this mimicry?
I'm feeling future shock; heavy future shock.
