> On a spaceship one can create an environment tailored to our needs. That seems pretty optimistic. I think the reality would be exactly the opposite: resources are extremely limited in space and there is much less room for error, which pretty much demands an authoritarian society where individual choice has to be severely curtailed, and the environment would be constrained by the same lack of resources. Of course, the level of technology in the ship would determine just how bad it would have to be, but I don't see any future within the next thousand years or so where you could have an environment on a generation ship anything like what we have on Earth.
