I'm not a fan of AI "art" at all, but this particular attack does leave something to be desired.

Beyond aesthetic judgements of good/bad or intentional stance re: communication with others, there is such a thing as "process art" which could also be described as communication with oneself, or as kind of being locked into conversation with the medium, or with the universe. People will get distracted here and want to fight about whether Pollack is good, but I think that's missing the point. It just happens to be a very direct way of engaging with the dialectic tension of order / chaos that's incompressible, irreducible, and completely without substitute.. and that's just one of many dialectics you could explore.

Another self-communicative aspect of art is about exploring the limits and mastery of technique, where the details and result per se don't matter much. You can see this with a bunch of dorks building useless programming languages and doing amazing stuff with them, or see it with a smith at a forge. Someone will say this is about being a technician or a craftsman, but I'd say no, those activities typically have a practical purpose. Especially if you're doing this for the joy of it without even caring whether you're actively learning something you can apply elsewhere, then it's probably art.
