I also agree that artist employment isn't sacred, but after extensive use of the generation tools I don't see them replacing anything but the lowest end of the industry, where they just need something to fill a space. The tools can give you something that matches a prompt, but they're only really good if you don't have strong opinions about details, which most middle tier customers will.
