I thought Aurora was flawed in one major respect. The novel suggests that galactic expansion is impossible for civilizations because foreign star systems will have alien pathogens or other environmental factors hostile to human beings. So far, so good, an enjoyable explanation for the Fermi paradox and a contrary view to the optimism in KSR’s earlier novels about terraforming planets. But in Aurora KSR also decides to make the generation starship’s quantum computer evolve to become sentient. Now the obvious question to resolve is that machines wouldn't be susceptible to all the biological challenges that KSR listed, so why can't civilizations expand to other solar systems in machine forms? But KSR doesn't grapple with that at all, it is completely passed over.

Well, the pathogen is not the reason but one of the reasons. The message is clear - if not one thing then another will get you. Again, I feel that this is a metaphor for expansionism in general, not necessary galactic expansionism in particular. > But in Aurora KSR also decides to make the generation starship’s quantum computer evolve to become sentient.

And this is not a bad thing in my view.
