> The theory here is that the property and social relations of long-term space-dwelling (especially over generations) would be of a fundamentally different type compared to the norm on a planet; the mutuality of dependence involved in an environment which is inherently hostile would necessitate an internal social coherence which would contrast with the external casualness typifying the relations between such ships/habitats. Succinctly; socialism within, anarchy without. This broad result is - in the long run - independent of the initial social and economic conditions which give rise to it.

And that feels kind-of Star Trekkie in its optimism that humans can ever live in peace with one another, and that "socialism" (however you care to define it) can ever be successful - capitalism fosters innovation. Perhaps the only way Banks' vision of the future could be successful is do exactly what his books talk about and we just let the machines take over.
