It seems to me that robotics, by its nature, upends Capitalism. It doesn't imply a post-scarcity society, but each major drop in scarcity (hunter-gatherer to farmers, farmers to industrial) has created basically different societies with major rule changes. The introduction of robotics, especially if combined with fusion, nanotechnology, AI, and advanced biotechnology, would be on the same level as agriculture or industrialization.

Humans would redefine their usefulness. Economic usefulness would be for machines. Humans would invent new standards to measure their use.
