Agreed; O'Brien's boot metaphor was purest hubris. I don't know if I'd call civilizational collapse "positive", though. Surely things will get better afterward! Things always do, eventually. But, judging by history, we'll be in for a rather ugly interregnum in the meantime, one marked by the sway of Hobbes's dictum ("...nasty, brutish, and short"), by constant insufficiency in all the material necessities of life, and by all manner of short-lived but violent popular enthusiasms; in general, a world fit only for those young enough to love chaos, and one harsh even for them.
I don't fear for the species; we're tough bastards and can survive anything short of heat death. But I would like to think that some day we'll work out the trick of anakyklosis and finally have done with dark ages.
