Overall, it’s hard to tell whether this story comes as a relief or not. Short version: the illogicality and inconsistency with which the national power grid has built – that is to say, there isn’t a national grid – means that we are in fact more immune from a Robbian-style global guerrillas attack. The grid is too shitty to be vulnerable.
Which is good for our security short-term, but bad for long-term nationwide electricity. The real question is how do you duplicate the success of of an unplanned system? How do you engineer unpredictability? Answering that will be one of the major challenges of the 21st century.
