re: #321 Fozzie Bear
Who said you need to get tens of thousands of people off the planet any time soon? That would be absurd. We need to develop the tech to trivialize getting there first. We need A.I., materials tech, energy generation tech, etc, etc.
We are going to end up in space if we don’t kill ourselves as a species, eventually. Not all of us, of course, but people breed quite rapidly.
I can see space from my house…
