It may not be obvious from the context and the limited excerpt, but in the book Sapiens, the author is careful to make the point that this is not an invitation to revert to the hunter/gatherer lifestyle, in fact, we're past the point where that's a possibility. Rather we have to innovate our way out of the predicament we find ourselves in (the irony of fighting fire with fire is not lost on me). But in my mind, it makes this a perfect quote to consider on a techie site.
