I still think we are more or less on the same page. I also agree with your position on NFTs. Nevertheless, "machine-generated art" as you've called it IS legitimate creation, just like canned baked beans is legitimate creation, just like the act of making scrambled eggs is creation. Notice that I never mentioned anything QUALITATIVE about the process. I've never referred to these works as "art" (however you'd like to define that) but "illustrations" which is all they are and again, for the most part, they are visibly AI...but there are exceptions, rarely without human intervention (retouching). If someone wants to sell their AI-generated illustrations, what's the problem? Same with NFTs. What do I or you care? It's your moral obligation to part a fool from their money.
That said, since we've veered way off course of the original question, MY PERSONAL OPINION is there is next to no expression of the human condition (define that as you will) in StableDiffusion/Midjourney/whatever-engine "art" and is merely ("merely," he says!) putting the "infinite monkeys theorem" into practice. While chance and chaos is good (and not only in art), a foundation is always necessary. If "you", untrained in composition, art history and materials, you think describing images using a certain language/method is "art", become a writer. We're all waiting for your bestseller.
Have a wonderfull day and thanks for the chat!
