Every art form you've mentioned still had to be created by a human. The only difference was how. Was it oil on canvas or stylus on Wacom? Was it film or digital? Is the synthesizer analog, digital or a VST plugin, and does it really matter as long as someone is still playing the keyboard with his own two hands?

AI has removed the human element entirely. This is a paradigm shift, and there's more merit in bemoaning using AI to wholesale generate a "photo" than there ever was in a film photographer bemoaning digital.
