I'm not saying they have to or should do that; maybe they just don't care enough. And that's fine. But the option is there.
If someone prompts an AI, "generate an image in the style of Picasso's Guernica", then the result of that, by definition, has no deeper meaning. No emotion went into creating it. The person who prompted the AI could make something up, but it's hard to say what's "real" there. Even if they were to guide the image generation by describing their own emotions, the result wouldn't really be their own expression of their emotions. It would be the AI's probabilistic guess as to what those emotions look like on paper, when rendered using Guernica's style, based on a mish-mash of thousands of different artists and art history research. Ultimately it just doesn't mean anything.
I accept the idea that a talented artist could guide the AI with much deeper specifics about what to "draw", how to draw it, etc. And maybe -- maybe -- that's something that would convey the human's emotions faithfully. But I don't think that's what we're talking about here.
> There's a story that, IIRC, was told by Brian Enos, where he was practicing timed drills with the goal of practicing until he could complete a specific task at or under his usual time. He was having a hard time hitting his normal time and was annoyed at himself because he was slower than usual and kept at it until he hit his target, at which point he realized he misremembered the target and was accidentally targeting a new personal best time that was better than he thought was possible. While it's too simple to say that we can achieve anything if we put our minds to it, almost none of us are operating at anywhere near our capacity and what we think we can achieve is often a major limiting factor.

Art is nothing like shooting. My first instinct looking at Guernica is that I also feel nothing, but one can limit oneself and say: if I feel nothing initially, I will feel nothing at all. If you prime yourself to be open to an experience of putting yourself into the shoes of the author, you might start feeling something.
Your life will be richer if you learn to take more things in, and to appreciate them. And it may require actual learning! And practice!
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.
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.
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.
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.
