It's about how a system can observe changes, react to them, make decisions to further itself (not any particular values), and act on those decisions. Think about a cybernetic OODA loop. Systems that do so will outcompete and replace those that don't.
Capitalism is all about that. If there's a dollar on the ground, someone will pick it up quicker than someone who has to petition some other agent to acquire a lock. And if two agents can engage in a mutually productive trade, they will not only fire together but also modify the system such that they will wire together in the future to more efficiently acquire limited resources.
All that is solid melts into distributed representations. In a way, he takes all the smartest critiques of capitalism and decides, well, capitalism is going to win, so we might as well embrace the state it converges to. Or not, but it doesn't really matter.
