We have known this genetic bottleneck nearly brought us to extinction for a long time. But the number has been the question. We’ve held to the estimation that it was under 10,000 for as long as I can remember. And 1200 certainly seems believable. Even if terrifying.

The reason I follow this line of research is rather simple:
“Nature is a vast irradiated hostile wasteland, and the solar system, the climate, geology, flora, and fauna try to kill us with frightening regularity and near frequent success. So the need to ‘transcend’ the planet isn’t really an option, nor is returning to agrarian age ignorance that time is an endless cycle. By every statistical measure we have under 15k years of probability before another catastrophic crisis. And we lost over a thousand years, from 500ad to 1800ad to superstition of our own making already.”
