    Actually, on the Delta Airlines computer shutdown, there's a bit of finger pointing but the official reason is a "power failure" due to "defective equipment."

    So I guess it depends on one's perspective -- is a failure in 100+ year-old technology "incomprehensible technology" or is it simply "somebody should have done a better job?"

    IMHO, the real challenge is anticipating all the different ways a system (whether "incomprehensible technology" or something as simple as a neighborhood street) can fail and then providing -- and testing! -- a workaround or backup strategy.

    Finding or anticipating all possible failure modes is why software testing is so incredibly difficult....

    There are some other pearls, but these stand out
    Brad, the story was written in the 50-s and those were simpler times. Still, I find it surprisingly accurate description how civilisation becomes critically dependent on incomprehensible technology, of which GPS is a good example. Or, fresh from the press, Delta paralised by some mysterious, but no doubt technology related reason.
