It's the nature of negative black swan events that there's always a reason to believe they won't happen right up until they do. If you hold these beliefs over a long-period of time, based on long-term societal trends, "your whole world-view comes off as a bit prepper / Great Replacement-crank". If recent events bear you out, it's Availability / Recency bias. If the events actually come true, then we won't be discussing it on an Internet message board, we'll either be dead or spending our effort trying to survive, in a perverse form of Survivorship Bias.

Nevertheless, we know from history that these events do occur, and they occur much more frequently than those of us alive now believe (again a form of survivorship bias - folks that don't live in a time of peace tend not to survive). The 250-year stability of the United States - and the 75-year Pax Americana after WW2 - is a historical anomaly. The article gives a bunch of reasons why the 2020s will be different, financially, from the 1980-2020 period, and I gave a bunch of reasons why it'll be different sociopolitically. You can choose to believe them or not, but I (and Dalio) at least explained the dynamics that lead me to believe them.
