That's a great quote and explanation of why the process of making art is important for those who participate in it. However, it does not claim that the _entire point of art_ is that process, which is what I am refuting.
I think it's important that artists keep doing actual "traditional" art and grow in the process if they have any motivation to do so. But I feel strongly that asserting that AI art or art that hasn't involved some arduous process, doesn't have any value, is nonsense. Because that means that enjoyment or communication from art is not just much less important than the development of the artist, but worthless. It's kind of a classist or elitist and self-aggrandizing view.
