You can't argue about taste.
You may like the music of Zombie by The Cranberries, but I'd say it belongs to the complete appreciation of it to know that it's about the Irish Troubles, and for that you need some background knowledge.
You may like to smoke weed to Bob Marley songs, but without knowing something about the African slave trade, you won't get the significance of tracks like 400 years.
For Guernica you also have to understand Picasso's fascination with primitive art, prehistoric cave art, children's drawings and abstraction, the historic moment when photography took over the role of realistic depiction, freeing painters to express themselves more in terms of emotional impressions and abstractions.
Let's take Zombie by The Cranberries as an example. I really liked this song as a kid, still do, I think it has a great sound. The difference is that I now speak English, can understand the lyrics, and could look up the historical context. Ever since I did so, listening to it has never been the same, and not in a good way.
There are also examples which are not going to be so specific to my opinions. Kendrick's Swimming Pools was a house party staple, despite the song carrying heavy anti-alcoholism messaging. The contrast is almost comical.
For a different example, let's consider temporal contextuality; you describe Guernica being reliant on this. When I try to think of an example, I'm reminded of vague memories of shows with oddly timely subtitles. Subtitles that referenced things that were very specific to the given cultural moment, basically memes, but vanished since. It's not a good experience, and I'd say it would be reasonable to chalk such a thing up as a critique, rather than something worthy of praise.
This is also why I half-seriously referred to the piece being "aggressively pretentious". Rather than coming across as something I'm just genuinely missing the context for, it comes across as something with manufactured sophistication (which then I am indeed missing the context for, but unapologetically). This might still be a mirage, but I think with how pretty much stereotyped this experience is at this point, I'd imagine there's got to be some truth to it at least.
This is not to say that eternal themes aren't important. But art is a kind of social technology that mediates between people in given cultural contexts. Part of "the great conversation" across the ages, the part you can't express in logical essays or propositions. And the eternal themes pop up in different "clothes" at different times. Once you have the key to unlock them, you do discover the same human nature and human problems operating underneath as ever.
And the beautiful cathedrals are not simply beautiful for beauty's sake but their art often conveys very specific theological claims, often hotly debated at the time. Or the choice of subject may have been outrageous or novel at the time but mundane to us now.
Liszt's music may move us even today, but we can't quite appreciate it in the same Lisztomania way as it was then, when it was fresh and novel.
Take U2's October as a nice example. (You mentioned Zombie, incidentally one of my favorites, the anger and frustration in there never fail to hit me, I can't listen to it too often for that reason), superficially it is a very simple set of lyrics (8 lines I think) and an even simpler set of chords. And yet: it moves me. And I doubt any AI would have come up with it or even a close approximation if it wasn't part of the input. That's why I refuse to call AI generated stuff art. It's content, not art.
I would have thought similarly, but actually feeding 19th century poems to Suno and iterating on the prompts several times I got some results that moved me emotionally, as in, listening/reading the words with this musical presentation enhanced my appreciation of the poems and it felt more visceral. Like making angry revolutionary poems into grunge brought it closer and less of a "histoic", "bookish", "dusty" thing.
Anyway, this gets hairy quickly, that's why I chose to illustrate with a crappy recording of a magnificent piece that still captures that feeling - for me - whereas many others would likely disagree. Art is made by its creator because they want to and because they can, not because they are regurgitating output based on a multitude of inputs and a prompt.
Paint me a Sistine Chapel is going to yield different results no matter how many times you would give that same prompt to Michelangelo depending on his mood, what happened recently, what he ate and his health as well as the season. That AI will produce the same result over and over again from the same prompt. It is a mechanistic transformation, not an original work, it reduces the input, it does not expand on it, it does not add its own feelings to it.
It's a bit like when people describe how models don't have a will or the likes. Of course they don't, "they" are basically frozen in time. Training is way slower than inference, and even inference is often slower than "realtime". It just doesn't work that way from the get-go. They're also simply not very good - hence why they're being fed curated data.
In that sense, and considering history, I can definitely see why it would (and should?) be considered differently. Not sure this is what you meant, but this is an interesting lens, so thanks for this.
It's tiresome to read the same thing over and over again and at this point I don't think A's arguments will convince B and vice versa because both come from different initial input conditions in their thought processes. It's like trying to dig two parallel tunnels through a mountain from different heights and thinking they'll converge.
There is a good part of the series Remembrance of Earth's Past (of which The Three Body Problem is the first book) where the aliens are creating art and it shocks people to learn that the art they're so moved by was actually created by non-humans. This is exactly what this situation with AI feels like, and not even to the same extent because again AI is not autonomously making images, it's still a human at the end of the day picking what to prompt.
I think that 'dutch people skating on a lake' or 'girl with a pearl earring' or 'dutch religious couple in front of their barn' without having an AI trained on various works will produce just noise. And if those particular works (you know the ones, right?) were not part of the input then the AI would never produce anything looking like the original, no matter how specific you made the prompt. It takes human input to animate it, and even then what it produces to me does not look original whereas any five year old is able to produce entirely original works of art, none of which can be reduced to a prompt.
Prompts are instructions, they are settings on a mixer, they are not the music produced by the artists at the microphones.
