The original question was "is human art more of greater value than AI art?"By that metric it can have artistic value becuase it's a human operating the AI. As long as they have something clever or meaningful to say with it, it can be meaningful in the same way the toilet is.
For example, I'd argue that the way the Twitch streamer and youtuber wayneradiotv uses it has artistic value because he uses it cleverly. Maybe not a huge amount of artistic value, but at least as much as standard youtube fare
