> The idea behind a generation ship is that the initial crew would live, reproduce, and die on the ship, with their descendants continuing the journey until reaching the destination. What a shame -- their basic premise is grievously mistaken. When we have the means to launch interstellar pioneering craft, people will have figured out the most logical, sustainable approach -- launch a set of frozen embryos, not a set of arguing adults. The craft would gain speed toward a suitable target, then drift for centuries, no need to waste resources on living, arguing human beings. When the destination is reached, the craft will land and spawn a human crew at the destination -- using artificial wombs and robots to guide the children into adulthood. Someone might object to the idea of letting robots teach humans, but hey -- look around. It's already true.
