There you have it. Is it art? Kinda(?).
What we forget is that this is
not an AI work (guessing here, but I doubt an AI spontaneously created it of its own volition). It is the work of someone who engaged in conversation with the AI directing it what to do, trying and essaying over and over again until the AI produced what they wanted. The level of detail shown has required a similar level of attention from the author(s). Not that much different from any other digital art, for instance: instead of picking a brush you tell the computer to simulate one for you. You may move the "simulated" brush with a mouse of tablet, or with voice commands, but if digital art is art, if non-oil paintings are still paintings, then...
Now, for
me: that doesn't mean it is Art. When I scribble a series of scratches on a sketchbook to make a < 5 minute sketch, I do not consider it Art, not intend it to be Art: most often than not it is a set of quick notes that by themselves look awful, with little attention to composition or quality, and anybody seeing them should notice that. Similarly, that it is made with a pencil, brush, computer program or AI is of no consequence, it is the qualities of the final work that matter. So if for you this works "kinda", it is "kinda" art. If it is "awesome in detail but dull in content", then it is "awesome in detail but dull in content" art, if it is a plagiarism or a lookalike, so it is, & so on.
OTOH, I remember reading last year (methinks) that there was a second Mona Lisa in Madrid, apparently from the same workshop and dates, and that it seems to be the earliest known copy of the original -mimicking in detail the whole creative process (hidden corrections included) meaning it must have been done simultaneously to the original. What is certain is that the "genius" was in the first one -whichever it was-, copies didn't require as much genius, just "technique" (and the technique in that copy was lesser than the Louvre one). The first was Art, the others might be "lesser art".
What I think I am trying to say is that there is not just a definition of "Art", but a continuum that is often blurry and subjective. So, the original question can only be answered in a similar, blurry and subjective way.
