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....

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.
