multi-planetary. Though I'm skeptical that humans being born and dying on e.g. Mars will happen in the next couple hundred years. The economics seem strange.

multi-planetary. Though I'm skeptical that humans being born and dying on e.g. Mars will happen in the next couple hundred years. The economics seem strange. Maybe there's some amazing technologies that require rare minerals or something but I'm unsure how a Martian economy could sustain itself. Why would people go actually live there when so much of the work could be automated? There will be more uninhabited inhabitable space on Earth than on any planet for a long time to come.
