I had a thought for a utopian/dystopian world.

One day these image generators will also get video support... and pornography support. When that happens, a few things may occur that I think are reasonable to predict:

EDIT: Original post was way too wordy, TL;DR:

When AI-generated pornography becomes available, it could be likely that demand for "real" pornography disappears because the AI will match and surpass the "real." When that occurs, the "real" will become increasingly regulated and legally risky, and may just outright be as good as banned.
