Starting with the early Xerox machines, all technology contains a hidden anxiety detector. When your anxiety goes up it makes the machine more likely to malfunction. This has been demonstrated by generations of students working on their projects/papers at the last minute.
I understand that this seems inconceivable, but, if you don't believe it propose another theory that explains why the more you need the technology the less likely it is to work correctly.
