This novel is a generation-ship story. There is a complex computer program that maybe approaches AI levels. I think it was in the discussion of this that KSR brings up several times various cognitive errors:
ease of representation, probability blindness, overconfidence, and anchoring.Very interesting stuff, I would have liked to have seen it explored in more depth.
Even those aware of the existence of these genetically inherited cognitive errors cannot seem to avoid making them.
The plot has several interesting twists - and probably some bad news for the concept of exploring other planets. It is a great read, I don't think KSR can create anything else. We just need to get him pointed back at post-scarcity, anarchist, socialist utopias!
