No, this is a totally fair response. That was probably the core error in my argument.
Some people, perhaps most, will enjoy AI art. Artists are at risk of displacement too.
But a subset of art appreciators hold firm that the creator is an essential aspect of the work, and I don’t see that conviction fading.
How large this subset is, I don’t know. But they also happen to be the world’s tastemakers and trendsetters. Their beliefs largely shape our aesthetic world, so their influence may only grow.
