Comment of the day
Imagine living in the last days of the Roman empire, and knowing it (and many of them did) [I don't see how that's knowable. But fin de siecle? Sure]. Maybe even figuring you know how to save it, but knowing as well that the politics and economics are so dysfunctional that it just isn’t going to happen, even if it’s theoretically possible. Or imagine living in Sung China, as the Mongols bear down. You may have decades, but you can guess that they are going to win… (though the Mongols weren’t bad to be ruled by, it was the conquest that sucked).
Which is to say, well, humanity’s been there before (including one point where we were down to maybe 15K population, iirc.)
What could go wrong?
Well, almost everything. But who knows? Maybe the choke point that the 15K get through this time is somewhere out on the margins. And maybe Ian is wrong. Pessimism of the intelligence, optimism of the will. Because in the long run, we're all dead!
NOTE Slightly edited. It's going to be helpful, I think, to those who make it through the chokepoint that they be able to write. Though I don't know what language, or even what script. So it's important to save as many as possible...
