Does this shed any more light on whether it's valid for the author to name 2008 as a flash crisis? The taleb comparison survives on the idea that talebs thesis (long tail events are underestimated) is the same as negative long tail events happen quickly. So I don't think that sheds much light. On the financial side, those look like two arbitrarily long term periods where you couldn't 100x in O(weeks) by a long tail bet on the negative side - but alas, arbitrary. ex. stonks traded sideways in 2021 but I made an absolute fantastic amount of money in about 3 weeks in Feb/March 2020, as an accident, buying puts to poke fun at this new silly mistaken trend of thinking options were for retail investors (ah, I was so young and innocent)
