I am extraordinarily skeptical of essentially the whole comment except this. Economies are very complicated systems composed of many non-rational actors. All economics is voodoo IMHO. It's akin to try to predict the fluctuations in current on a motherboard's bus without having any conception of what program is running. Total guesswork on top of a system more complicated than human understanding.

We want to understand economies in terms of pipes and pressure and the complexity-equivalent of simple machines, when in reality the future is going to be dominated by black swans: crazy things like cryptocurrencies, cyberattacks, once-in-a-millenium climate/weather events, political revolutions, and fads.

Chaos, indeed!
