Anyway, this gets hairy quickly, that's why I chose to illustrate with a crappy recording of a magnificent piece that still captures that feeling - for me - whereas many others would likely disagree. Art is made by its creator because they want to and because they can, not because they are regurgitating output based on a multitude of inputs and a prompt.
Paint me a Sistine Chapel is going to yield different results no matter how many times you would give that same prompt to Michelangelo depending on his mood, what happened recently, what he ate and his health as well as the season. That AI will produce the same result over and over again from the same prompt. It is a mechanistic transformation, not an original work, it reduces the input, it does not expand on it, it does not add its own feelings to it.
