It’s also worth noting that Strauss, Howe, and Turchin all repeatedly stress in their books that firm dates aren’t a guarantee, that sometimes the cycle doesn’t line up correctly (like the Civil War cycle), and that none of their words are meant to be taken as literal predications so much as cautious warnings that history often rhymes.

Having finished both The Fourth Turning and End Times recently, Strauss and Howe’s specific guesses as to what might fuel the next crisis are laughably off track even if their broad strokes still paint a compelling (and at times, frightening) picture, while Turchin feels more prescient in his observations.

Ultimately, though, Turchin has the better message: even when a crisis destroys an empire, the world continues onward. That gave me some bleak hope to hang onto.

The Limits to Growth predictions are laughable.

I think that they Simon–Ehrlich wager showed how laughable they were but I guess we have to revisit every couple of decades.

Yeah I was fully expecting this site to be making fun of all the wacko conspiracies about armageddon, such that it would make me feel better. But instead, the "Limit to Growth" summary seems entirely plausible.
