If I ask a comics guy their favorite comic artist they aren't giving me back editors names. They will have favorite editors, or even editor artist pairs, but the artist remains distinct from that.
I simply posited that commissioning a piece of work does not make you an artist. Having art generated for you to your taste is not 'making art'. Hiring an interior decorator to decorate my house does not mean I decorated. Ordering off a menu and requesting extra cheese does not make you part chef.
A better blurring for your argument would be the use of session musicians. If I say I love The Beach Boys, how much of what I love is session musicians work versus Brian Wilson's? Is he the artist that I enjoy? But that gets back to it, doesn't it. We as humans want to connect art with it's creator. Why? Because art is some reflection of something. Art is 'life is a shared experience'. AI 'art' is not part of that shared experience. I want to connect with Brian Wilson. But I don't connect with some music critic who writes about Brian Wilson's music even though we both connected with the same artistic work, even if I learned about the work though the critic making my relationship to them just as important (I wouldn't know it without them). There being an artist in the middle improves/transforms it/means something (what it means is what is up for discussion).
A pretty crystal is just as pretty as a piece of art, but it is not a piece of art. AI art might be more like the crystal. It might contain beauty/interest/capture attention. But it's not connecting with someone's creation, with intention. I have a local museum and I love exhibits that a specific curator there has focused on more than ones they didn't touch. But that doesn't make them an artist. AI 'artists' fall into that category.
