I don’t know how to say this any more plainly: anyone who predicts such things is 100% full of shit. It’s a random process. Anyone able to predict this with a significant degree of certainty would quickly become a multi-trillionaire. Insanely huge financial institutions employing thousands of PhDs were not able to predict the last big one and many of them would have collapsed without government’s help. What makes you think anyone has the foggiest clue as to the timing and severity of the next black swan event?
