The difference is the level of human input. It takes NO skill to write a prompt for two hours. It takes observation, timing, attention to detail, and dedication to capture good photographs. These skills are even MORE important in creating art by hand, in addition to good hand-eye coordination and understanding of artistic principal.
A.I produces NONE of that. It takes data from millions of REAL artists and spits out a Frankenstein image the "based proompter" could NEVER actually produce, because his brain cells are so decimated that he needs a machine to think and produce FOR him.
