I know you understood it.

Your whole argument is nothing more than unfounded human exceptionalism. AI can't do stuff because it is not human. Yet you fail to show any significant difference between AI and human. Look at the history of art. Humans just follow patterns and copy other artists too. You don't see new trends emerge from nothing, it's all just a slow evolution. Or go over to https://www.artstation.com/, half the stuff on their is just fan art, celebrities or generic sci-fi/fantasy/military stuff that can be replicated by AI in a couple of seconds. Where is that magical human originality?

You compare the best of the best that billions of human have managed to produce over hundreds of years with what AI farted out in 10sec and than complain that AI isn't up to par, completely missing that about 99.9999% of those humans would be completely useless in producing high quality art.

Humans, again.

Human deciding to hand control over to AI is not humans being in control. That's humans losing control.

It’s not just making it bigger and longer.

Well, for a lot of art it is. Short movies being short. Comic books being black&white. Indie games using pixel art. None of that is because the people making those things want that, it's because doing it bigger and better is outside the time/budget that they can afford. AI art makes things possible that used to be impossible on a small budget. I welcome that.
