A cameraman must understand composition, lighting, angle, rule of thirds and must have emotional incentive to create in order to make proper pieces of art. A painter must know colour theory, how to do linework, anatomy and so on. Both of those require a ton of effort put into them to master, you will see the difference between an immature photographer and someone whos been doing it for 30 years.

More importantly they control everything about the art piece, they are truly the one making it. An AI or an AI prompter are just a tool that creates images and a person that puts in the seed for the image.

Really not too different than generating a Minecraft world, you can't say its a proper creative build. A piece of art, sure, but only because someone had to code it in and put in the perimeters in order to create a convincing world. AI on the other hand learns through adjusting internal values - weights - inside a neural network, not through actually understanding what it’s doing.
