I find Techno-Utopianism vaguely amusing. We are currently residing on a better "Worldship" than we could ever engineer, and we've been knowingly destroying our life support systems in the face of ever-growing warnings from scientists. Ignoring the other planetary crises we face - biodiversity and ecosystem collapse - our continued existence on our planet depends on somehow sucking billions of tons of CO2 out of the atmosphere and storing it somewhere, somehow, forever. This is trivial compared to colonies in our solar system, much less interstellar travel. Ignoring the question of technological and engineering feasibility I propose the hypothetical World Ship Thought Exercise ( 100,000 people (on average), 10k year journey, each individual lives around 100 years). How would the population be structured? Would it be democratic? How would crime be dealt with? How would people decide who does what? Would there be castes? An underclass? Would there be rationing? Could there be homeless? What about birth control? What if a portion of the population simply didn't want to have kids or didn't have enough to replace the population? How would religion be dealt with? Would, could and/or should a 10k long civilization remain static?
