There are really two fundamental paths. History is going to bifurcate along two directions. One path is we stay on Earth forever, and then there will be some eventual extinction event. I do not have an immediate doomsday prophecy, but eventually history suggests that there will be some doomsday event. The alternative is to become a spacefaring civilization and a multi-planet species, which I hope you would agree that is the right way to go. Yes?
