I don't disagree that experiences are data. The major distinction I'm making is that the human creative process uses more than just data, we have intention, aesthetics, we make mistakes, change our minds, iterate, etc. For a generative AI, the "creative process" is tokenizing a string, running the tokens through an attention matrix, plugging that into a thousand different matrices that then go into a post processing layer and they spit out an image. At no point does it look at what it's doing and evaluate how it's gonna fit into the final picture.
As for the rest of your reasoning, I neither agree nor disagree, I think we just don't have the same definition of consciousness.
