> If something planet-scale happens while we wait on a single planet, the entire species would not make it. I suspect even Musk doesn't believe this. I've never read/heard him talk about our species being wiped out. He usually prefers the much more vague concept of end of our "technological civilization".

He often does speak of humans being wiped out as a reason to colonize Mars. I think there is a strong humanitarian argument for making life multi-planetary in order to safeguard the existence of humanity in the event that something catastrophic were to happen, in which case being poor or having a disease would be irrelevant, because humanity would be extinct. I think 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, there will be some doomsday event. The alternative is to become a space-bearing civilization and a multi-planetary species, which I hope you would agree is the right way to go. Either we spread Earth to other planets, or we risk going extinct. An extinction event is inevitable and we’re increasingly doing ourselves in.

> He usually prefers the much more vague concept of end of our "technological civilization". That's a reasonable view too, IMO. If our technological civilization suddenly collapses for any reason, most of us here, and double-digit percentage of world population, will die a painful death. The lives of whoever remains won't be pleasant, and the technological civilization probably won't arise again for tens of thousands of years (given how we've used up all easily accessible energy sources). Life is very resilient. Humanity as we know it is not.
