But as the last four years have shown, you also have to allow for the possibility, or perhaps probability, that the world as we know it isn't ending

I mean, the 25 years episode of "right" economic ideology, coinciding with maxed availability of energy resources, will not last much longer. The financial system cannot keep up with adopting to itself. The snag is that people already forgot the "normal" world of before, especially strongly assuming it was the same as now. We will rediscover a lot.
