Jut recently, there was a thread discussing Persepolis, a series of autobiographical graphic novels by Marjane Satrapi (recently deceased) that depict her childhood and early adult years in Iran and Austria during and after the Islamic Revolution. People remarked it was deeply moving.
Part of what makes it deeply moving is the actuality of it. This is a human story based on actual lived experiences. How does an AI produce this?? If it came out later that it was written by an AI (assume for the purpose of argument that we had AI when it was written), then of course m=it's impact would be different.
If a seemingly powerful piece of non-fiction is later exposed as fiction, and AI written fiction at that, won't that change your perception of it? Or if a nice anecdote someone likes to tell is exposed as made up, I would hope that matters.
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?
