If the world population hits a ceiling (or starts to shrink), and corporations get more massive - reaching every citizen on earth, how can they continue to grow?
Assuming the typical pathways of acquisition/merger have been exhausted. Now you're looking at a world of abundance, and corporations must invent ways to generate demand.
So what if, robots could be state owned and be treated as a special class of robot citizens? They could earn a wage (or some kind of credits) and spend them for benefits like upgrades or repairs. Not just humanoids, all robots. With this, one could essentially create infinite demand-supply channels.
