These art AIs are very good at driving the point home that our DNN AIs are seriously capable. But those capabilities need to be nursed by ever-growing armies of people. True, maybe there is a limit to the amount of people needed to profit from coloring pixels in images, and maybe, just maybe, that ceiling is going to go down the more these artist AIs are used. But AI has the potential to break open areas we can't even imagine now. I for example have trouble imagining that in the time of the horses, there was an industry for traffic signals, another for transporting horse fuel between countries (but maybe there was?), another for teaching teenagers to drive the carriages and get their horse-driving licenses, and so on and so on. Although I don't know much about those days, maybe it was popular to be young and to horse around on top of a good steed.
Maybe we will be teaching our kids about how to survive in the jungle of wild AIs we have created for them, and teachers will be needed. Maybe we will hemorrhage AI-produced content, and in twenty years, there will be an industry for certifying that something is human-made (maybe a lesson to learn about how chess survived in the age of incredibly capable chess-playing computer programs?). Or maybe something else we can't quite see yet.
