I'm surprised this hasn't elicited more commentary. His thesis seemed to be pretty simple, that as we burn through our low-cost, high-return, surplus energy, our economics worsen. We then seek to remedy the problem through more energy-intensive complexity (The Complexity Trap), which doesn't work very well. He then seemed to argue that we got kind of a pass during the Industrial Age, because of oil's greater efficiency than coal, but that we won't be so lucky this time.<p>I guess I'm surprised someone hasn't come back with some well known counter theory? I kind of like this one, but I'm sure there are other interesting ones?
