It means that quantum computers are not special, they are just one kind of information system that deals with finite local information. The economy is actually a much better computer, since it also deals with finite local information, but it goes further by interacting with many other layers of such informational systems (cognition, technology, culture, etc) while a quantum computer is restricted to just its own level. It also means that no centralized AI will be better than a decentralized system involving multiple actors. It's very reassuring.

Nice. This is a first decent explanation that counters all that AI and quantum FUD. It’s very tiring to hear; I don’t see it as an imminent threat, but don’t really have any arguments to counter the FUD. For me, the simple counter argument is more decentralization.
I've had this same intuition for some time. We can see decentralized systems winning all around us.
