“You bastards!”
The world will end December 12, 2012 when Haruhi Suzumiya awakens to full godhood and remakes the world into her liking…and every time she changes her mind afterward.
But we won’t notice since we’re all part of the system, so don’t worry and relax.
The interesting thing is that Pournelle co-authored a novel based on the premise that the Earth suffers a new Ice Age, rendering Canada uninhabitable and everyplace else crappy, because ecofreaks put a stop to global warming just when we needed it. Which is an interesting premise for an SF novel, and clearly preposterous otherwise. And it was published in 1991. Yet Pournelle, despite being that extremely rare animal, a paleoconservative with a brain, and despite having had 17 years to learn better, still seems to believe it’s that way in real life.
