Ai can only ever be a mirror of our minds. It can't be more than what the programmer can feed it in training data made from other people's work from their minds.
Human creativity will diminish in value with or without AI, people are moving away from sweeping cultural changes and clever interpretations. People just want to look good and relate to ideas they like.
The tech is not in the drivers seat, it is just a facilitator made by our best minds. A moral movement "against" Dall E will be a futile attempt to call back horses bolted from the stables.
