The problem with this discussion is we are conflating artistic value with economic value. A music video can be valuable as art, but it can also be valuable as a tool for promotion or for generating revenue. If the goal is pure economic efficiency then an AI has the potential to create a music video more efficiently than a human. If the goal is to produce something that makes people feel some kind of emotion then AI will work against you. The same goes for code. I use AI to write code that I'm not precious about but if I want to feel proud of my work, you can be sure I'll write it by hand.
