I suspect the demand for human creative output will shrink, as AI generated content will be so cheap and prevalent, even as it will only ever be an imitation of human art. The same way that most people eat terrible, flavorless tomatoes from the supermarket, instead of the harder to grow heirloom varieties.

But I don't think human creativity is going anywhere. Unless there is some breakthrough that moves it far beyond anything we've seen so far, AI will always be trailing behind us. Human creativity might become a more boutique product, like heirloom tomatoes, but there will always be people who value it.
