Creativity, fundamentally, is overlapping memories of what you have seen already. Literally no different than any diffusion or transformer model.
You painting a piece of art or composing a song was really the functional output of billions of cells coordinating in unison, 100% subconsciously, and the thoughts that arose out of your subconscious were entirely (or mostly, to avoid free will debate) out of your control. Your output was the product of billions of years of stellar and biological evolution on top of millennia of human history and influence. You created nothing.
Soon you will have to grapple with the reality of what really drives your enjoyment of media, and part of that will be realizing that the human-ness never mattered at all.
Is beautiful nature scenery not beautiful because it wasnt hand-crafted painstakingly by a creative human? Of course it is. There is no intuition for the vast swaths of time it took to form, that is a modern human conceptualization that came long after we already found nature to be beautiful.
We have a biological pattern recognition tuned for beauty regardless of its origin. And there is nothing inherently unbeautiful about elegant software that can produce beautiful "art". Nor is there any justifiable, defensible, or intellectually honest way to argue that the human/effort element in art matters in any way besides perhaps portraying and conveying social status.
