Code is my art and is how I express myself. I agree that nothing that AI does is art.
I have written code myself that I deem beautiful and expressive. But I'm also a musician, and making music (and listening to it deeply) has given me such intense, mystic experiences, that they dwarf anything I've ever experienced writing code. It's also much harder to make good music because it requires a kind of courage and psychological constitution that is simply not required for writing code.
