I tend to think of it like this: keeping all humans on one planet and expecting long term survival is like keeping all of one's servers in one data center and expecting 100% uptime. And that data center has a tendency to be hit by extremely large rocks going very fast every now and then.
Yep, but just FYI, the common counter-argument on HN is that the survival of the species doesn't matter to the individual, so they still don't think it's worth spending money on.
Yeah, I never really figured out how to argue against that... it's kind of a built in urge for me, and it's not strictly logical except from a "I'm partly driven by my genes, which have been optimized to protect my tribe" standpoint. I figure most people have that, but if someone doesn't, you probably can't really make them care.
