I hope that as the quality of AI art continues to improve that the programmers continue to block the use of prompts that would create child pornography. I mean, the question could potentially even come up of whether AI pornography could even trigger legal repercussions, but there's still something to be concerned about if someone submits prompts for that sort of "art" anyway.
These pieces are amazing, even to the point the hands are done well (which is usually where the AI shows).
