Thanks for the article, it makes a lot of sense. Note that in this book, the doomsday scenario is predicted to happen 2 years in the future, so it's not quite the same as a natural disaster that has already happened. So I don't think it would look quite the same in terms of violence and how we've evolved. It's more like, imagine 30% of the population suddenly lose their jobs or something like that, you could probably see riots happening today.
