The prosperity engendered by high technology opens lots of economic room for nihilism, so we should not perhaps be too surprised to see it blossoming these days. But latter-day reproductive technology also makes it possible for nihilism to follow through in reproduction on its moral commitment to death. I.e., it enables nihilism to delete itself from the population. Never before has nihilism had this power to enact its own ultimate conclusions in concrete acts. Until recently, even most nihilists who ended up killing themselves also reproduced themselves in the meantime, willy nilly.
Mutatis mutandis, then, the population of nihilists should be set to crash, just as that of the Shakers crashed.
