He says no. Probably enjoying one last sunset outside before closing the hatch! I can't help but wonder about our h n founders, safe in their bunkers in NZ, reading dog eared copies of The Soveiregn Individual. And then I wonder about all the Ukraine war news stories leading up to this being and flagged and burried here. I hope it's just coincidence. As I have said before, they think they can survive nuclear winter, no problem. But those assumptions are built on test of single small bombs. 10,000 going off at once is an order of magnitude worse, and might easily produce surprising effects. Science is always finding surprises in old experiments when they crank the power way up.
And I am no HN founder, but I live in Eastern Europe. NATO planes and helicopters kept flying overhead all day and my house doesn’t even have a basement.
So I bet we are closer to the danger than you are. And I also bet that the ones doing the flagging and burying are other brave "class warriors" and "eaters of the rich" who can’t accept that their beloved ideology has created monsters like Putin while the capitalism they despise has given the world prosperity, (relative) peace and Elon Musk (the last one's a mixed blessing, I admit).
PG if you are reading this, I love you really, man. And if there's any room left down there for a resourceful fella, I will work for bunk and board. (In fact, I've been stockpiling tins since Feb 20, so I only need the bunk ;)
