It comes under the category of "generative art". It isn't intentional or self-expression, regardless of what the prompt engineers may kid you. Is it "art"? Sure. Is it traditional art? No.
Artistry is a beautiful thing. It's also why I love hearing from industrial designers on how they arrived at their design decisions, challenges they faced, intent, nuances in the design you might overlook that were difficult etc.
Unfortunately, short of more behind-the-scenes material and interviews, the only way to really get a feel for it is looking at their body of work as a whole. The great ones always have a specific style that they refine or evolve over time. It's unmistakably x.
I have to say, I've yet to see any AI artist hit a signature style, and I've yet to have an AI generated piece of art move me emotionally or conceptually.
Are they interesting? Sure. So's glitch art, but there's not much substance to any of it, and I remember none of it. Intent and self-expression is such a huge part of art.
Can you imagine what Hitchcock would say about AI anything? He wanted it 100% his way.
No, it isn't intentional, it's generative. StableDiffusion DALL-E, MidJourney et al are quite literally by definition a generative art model. This isn't up for debate. That is quite literally how they function.
