Well in an argument between "everyone should die by 150 years" and "lets have the happy problem of people not dying of old age" I'm in the latter camp. Similar

Well in an argument between "everyone should die by 150 years" and "lets have the happy problem of people not dying of old age" I'm in the latter camp. Similarly having all of your species susceptible to any out of context problem that destroys a planet... yeah planetary existential risks are low probability with game ending penalty I'd like to see mitigated.
- Retra 9y agoSure, but if you put half of humanity on Mars, you'd clearly be increasing our risk, as the difficulty of surviving on Mars is nearly insurmountable. If you want people on other planets, they need to be self-sustaining. And if we can't even be self-sustaining on Earth, why would we be elsewhere? We're a very very long way away from being able to survive if Earth fails. It is foolish to bet on any kind of interplanetary survival strategy at this point. Getting humans to other worlds is by far the easiest part of that equation.
- GCU-Empiricist 9y agoI wouldn't put half of humanity anywhere right now. You just need enough to keep a population (with immigration) after they face a horrific mortality rate as they figure out how to lower the risk; hopefully highly trained and well equipped as sparse mitigation, but exploration and pioneering are hungry gods that will be fed human sacrifices. I'm personally more partial to an O'Neill cylinder or a Lunar colony than Mars and the lunar colony will probably come first, Mars is a big step backwards in delta-v, but yes the mass required to get that going is currently prohibitively expensive, and the biosciences are going to be really tricky.
