I agree in general. And I think the same argument can potentially be made about AI's 'creative writing'. Is it art? Is it truly creative?
The way I see it, the output of AI is never excellent and never comes close to matching the best human endeavor (or even competent human endeavor). If I ask it to write me a story it will be unable match anything I can produce myself. Having said that, I wonder if that is really the point To be useful, it doesn't need to be excellent, it simply needs to exceed the abilities of whatever particular individual is relying on it.
For example, when it comes to the generation of art, I recently tried out an image-generating machine (after someone linked to it on sff chrons). The result, at first glance, looked pretty good. Upon closer inspection, it wasn't good at all; forearms out of proportion to upper arms, background perspective all wrong, a few objects that didn't look like anything in particular. It didn't stand up to scrutiny. Having said that, it was still way better than anything I could have produced myself (not being that kind of artist). I might have been tempted to make use of the image for that reason.
Anyway, AI may come to take its place in the spectrum of art. Already, in the human realm, there is good art and bad art (subjective, of course). And already there is plagiarism, copying and art that is highly derivative (
