O.K., none of this is actually happening — I’ve yet to lay hands on a pair of Google’s ballyhooed cyberglasses. In fact I’m only vaguely interested in head-mounted technology, whether it’s coming from Nintendo, James Cameron or Sergey Brin. It sounds — and every time I’ve tried it, feels — like a compromise on the longer road to implanting subdermal CPUs and hardwiring our optic nerves.
