My response to wearable computers has always been "Why the hell would I want that?" But this gives me an idea that nobody will have to want them for them to become widespread. Instead, occupational health and safety bureaucrats may wind up mandating their use for workers in certain occupations so that their vital signs can be monitored for safety reasons. If the worker's heart rate climbs too high for too long then a buzzer will go off and force them to take a rest. Nobody will want this, workers or employers, but it will be forced upon both of them by safety rules.
