Essentially he's predicting a return of the Dark Ages and given the various fanaticisms today and the oil situation I wouldn't rule that out entirely although I think it somewhat unlikely. On the other hand, I think a return to a more locally based economy wouldn't be a bad thing either along with rebuilding our industrial infrastructure so we'd be far less dependent on imports. As far as energy, technology has the potential to provide new sources that aren't dependent on nonrenewable sources. In the long run the runaway consumerism will decline. I suspect he's directionally correct if a bit extreme.
