Yes exactly, art is simply a desire to express yourself and choosing to do so. A generative model isn't sapient and cannot express itself, and a person asking something else to create for them in whole cloth isn't partaking in self expression either. It'd be no different than calling yourself an artist because you commissioned someone to draw for you. In that case though, someone exists who could express something (the human who's drawing).

Art is not skill, techniques, or popular reception. It's the little rhythm you tap on your leg, the silly stickman with a gun you drew as a joke for a friend, the little dance you do when you're home alone. I worry this generative stuff will further push people from partaking in something so human because it simply "isn't good enough" and "I can ask something else to make a masterpiece in seconds anyway." The pretty little picture isn't what I'm here for, I'm here to share in your self expression—to see you be you! Anything less than that would feel grossly shallow to me.
