Is this another case of "let's pretend we didn't see it coming"? I took a look at the P/E graphs and it certainly looks like we are headed into dangerous territory--along with reduced resources and climate chaos. But it's hard figuring out how to time this mess financially: 2022? As late as 2026? And if there is a three sigma superbubble, does that lead to political turmoil?
