we insist that humans can do things better in some way or do things that ai can't do. some of that is true right now, but can't assume that will hold.
and yes it requires iterations and taste right now.
the idea that it can't happen in the future. or that humans are special in some way (which you are not claiming, but is a common claim) is the cope.
And in fact humans are special in a very straight-forward way: we share one thing with each other that no AI will share with us, which is our common biological ancestry and its consequences.
So, when looking at a human-made painting - which could look much worse than flawless AI counterpart - I'm not just looking at a painting, but I'm also thinking about what it took to produce, how much the artist was struggling to balance the need of survival with the need to create, how big was the price they had to pay, how it's similar or different to my own life, whether I'd be willing to pay such a price, and a lot more.
OTOH I don't care at all about the "struggle" of the ML model. I don't care about GPUs and TPUs sweating while climbing their "mountains". It might produce outputs that are aesthetically pleasant, but it will never be art.
