A machine might be able to make an objectively better thing, but that’s not what people are paying extra for. It’s the story about a real person applying their skills and effort to make it. Demand for that will likely never cease to exist. I bet it’ll just increase.
The famous painter Rafael ran a studio full of apprentices - he was a painter the way Thomas Edison was an inventor… it’s virtually impossible today to be sure how much of a Rafael painting was done by Rafael himself, though some of his apprentices had styles distinct enough for todays’ analyists to point to which part of which canvases they worked on.
