I'm not the person who responded, but I believe it came from a place of "what is art" (and you had used the word "artist").
My own position is that "art" can only be created by a human. AI can produce text, images, and sounds, and perhaps someday soon they can even create content that is practically indistinguishable from Picasso or Mozart, but they would still fail to be "art."
So sure, an AI can create assets to pad out commercials for trucks or sugary cereal, and they will more than suffice. Commercials and other similar content can be made more cheaply. Maybe that's good?
But I would never willingly spend my time or money engaging with AI "art." By that, I mean I would never attend a concert, watch a film, visit a museum, read a book, or even scroll through an Instagram profile if what I'm viewing is largely the output of AI. What would the point be?
I'll admit that there is some middle ground, where a large project may have some smaller pieces touched by AI (say, art assets in the background of a movie scene, or certain pieces of code in a video game). I personally err on the side of avoiding that when it is known, but I currently don't have as strong of an opinion on that.
