I am saying the an intrinsic component of art is the human context of it. You can call AI generated "art" by another name if you want, and enjoy it for what it is, but the reasons why you might enjoy it are different from the reasons you might enjoy human art.
Why do we still enjoy art in spite of the fact that we have photography? Or foot races even though we have cars?
We can keep throwing counterexamples at each other forever. You can find an endless number of examples wherein the provenance of an activity or piece of work is important to the enjoyment of it, and I can find endless examples where the provenance is unnecessary. What will this prove?
