The combination of those in proper size context to the astounding thing on that wall was... I dunno, very hard to bear? Chills and goosebumps. Just being in the presence of such genius. [Edited to add: I forgot! Many of the studies are clearly over complicated and colorful. And then you turn to see what was the final result. IMHO It's the same with genius software, in a different medium. Prose too, but maybe that's more contentious.]
There is no digital screen representation that can remotely approximate the psychic impact physical proximity to genius creates. I've felt this with many other greats as well.
I've sat alone in 3 different Rothko rooms. Damn. It's all I can say. You have to do it yourself. Tip: pan your eyes slowly while sitting in different corners.
Tongue-in-cheek aside, I do think I agree with you in that (1) art, as perceived by us human meatbags, is art because of the human element of it (if not in creation, then in perception), and that (2) AI absent explicit steering trends towards a rather bland medium.
But there’s art in everything from the blurry, out of focus, disposable film cameras, to a 5-year-old’s crayon scribble scrabbles, to the neon glitter themes we used to copy-paste over our geocities and xanga pages, and as frustrating as it is to our own sensibilities, an AI prompt “draw a pink elephant” isn’t all that different.
In addition, the communication doesn't need to be explicit or intentional. It can be communicating something antithetical to the artist's original intent like a blurry and out of focus photo. Or it can even be antithetical to the piece itself like a lot of modern art (Fountain[1] comes to mind). I'm also sure that the 5-year-old will happily tell you a story about why they scribbled what they did. I'm not diminishing any of those. But if all the person contributes is a prompt, the text of that prompt is the extent of their art.
When Picasso was interrogated by an SS officer about his painting Guernica, “Did you do that?” Picasso replied, “No, you did.”
