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.
That all depends on where you are “on the curve.” Above $500 for a painting to hang on the wall? People want at least a good story to tell people about it, if not a personal connection to the artist. Below $50? Yeah, price is king.
