Earlier quoted context omitted.
It seems to me that the human effort spent in creating the original images in an AI's data set is an important element to consider when thinking of the "difficulty" here.
Certainly, but those human artists were also trained on a data set their whole lives. Raise a baby with no training data set and they might produce a handprint on a wall or a rectangle of facepaint. There's a reason indigenous tribesmen don't spontaneously invent hyperrealism.
Image generating AIs are trained with massive amounts of images and text, however image generating humans train with much broader spectrum of experience.
Also, feeding a model tons of images created by humans (directly or by proxy) and claiming that AI is generating something completely new is a bit naive IMHO. Humans mix a much more broader and deeper experience pool to create things without prompts.
An AI model blurts out something derived from a corpus of images and text created by humans, that's all.
The technology is impressive for sure, and it marks a new era in terms of possibilities, but it doesn't take my breath away, sorry.
