Erik Brynjolfsson and Andrew McAfee, two MIT economists, recently wrote a book about this, called The Second Machine Age (here: <a href="http:&#x2F;&#x2F;www.amzn.to&#x2F;0393239357" rel="nofollow">http:&#x2F;&#x2F;www.amzn.to&#x2F;0393239357</a>). We&#x27;re teetering on the edge of economic shifts, and we have a lot of questions we&#x27;re going to need to ask about how people will live in a world where jobs simply aren&#x27;t available.<p>When 60% of the workforce is unemployable, either there will be massive unemployment, and the crime, poverty, and starvation associated, or there will be a massive paradigm shift in how we think about employment, money, and scarcity.<p>I&#x27;m hoping we get to the latter before the former.
