He is learning the hard way that AI is terrible for concept art.
AI can only create things that are a mash up of already available ideas, but if you want to create something new and specific to a vision it with turnarounds/details no, it's not going to do it. It is incapable of making small adjustments specific to a vision.
I like to use AI when working on my art specifically as an idea and reference generator. The AI can act as a fun way to jog the brain and come up with new ideas- but I have never been able to get it to give me exactly what I'm looking for.
