  • Dec 8 2012: Nanobots that can assemble themselves and help construct the colony. Inspired by Kevin Kelly's book. Seems that labs have already achieved success in prototyping replicative robots (regular-size ones though. Not sure if nanotechnology will be that mature in the near future). Advantage: minimum care (REALLY costly to maintain humans in colonies under construction). Downside: may lose complete control over the colony --- they virtually form an ecosystem of their own. And from our experiences on Earth we know it's just a pain in the neck dealing with ecosystems & environments.
