Actually, we are. Supply and demand belong to the sphere of necessity, they are means rather than ends. Are we merely feeding and clothing a species that exists for no other reason than to hunger and shiver?
Supposing the species was a ship, do we ask the passengers or even the engineers to explain the route? No, we look to the captain. And when our hypothetical ship is planet sized, and the infinite blackness of space is our ocean, perhaps even the captain is groping through the dark.
Artists and philosophers are the captains of the human ship, we are the organic priesthood of humanity, we are the sensory organs of the species. Humanity comes to understand itself through us, and through no other means. Even science can only elucidate the means, not the ends, Aristotle demonstrated this in his Nicomachean Ethics.
So you have it backwards if you imagine artists must satisfy the public, we are not here to entertain or sooth you, we are here to instruct you. Learn from us or perish, the choice is rather simple, and we don't really care if you choose the latter.
In regards to AI, we are glad it ruins the lesser aspect of art (mere decorative clowning). We hope AI will drive more artists to the conclusion we have arrived at, that we were born to lead humanity, not to subsist on its charity.
