I haven't watched a lot of Survivor or Naked and Afraid, but what I have seen makes me think there's more to survival than can be learned in a few months, let's say. And that's just basic survival. If we want to retain even an 18th century standard of living, we'd need to understand how to build steam engines, a cotton gin, etc., etc. I don't like our odds. To be clear: some people would survive. But my half-assed guess would be that the human population might drop to less than a million.
