The Lament for Icarus (2020) by Miao He

Can't speak for the person you're asking, but a lot of us who appreciate art appreciate the talent and skill it takes to translate a vision into whatever medium. Lots and lots of people get cool ideas, but artists take those ideas and bring them to life. Just typing the idea into a prompt box and having the result spit out doesn't seem like the same thing.

Art is a record of emotion; it exists to express something felt by the creator. When we look at art, we often feel connected in some way to whatever the creator was feeling when they made it. But AI doesn't feel anything; it just takes inputs and produces something that its machine learning algorthm thinks it will be rewarded for. It's like if you had a very deep and meaningful conversation with someone online, only to later find out you were being catfished; it leaves you feeling hollow inside. Sure, you could argue that the conversation itself still had some meaning to you even if your partner was disingenuous, but it destroys the veneer of sentiment and human connection surrounding it, casting it in a much darker light. And if you strip away the connection and sentiment from art, what do you even have left?

This is of course to say nothing of the massive amounts of theft from other human artists that AI art is built upon, but I feel that's not really what you were asking.
