"The next version," Dobelle tells me, "may have enough resolution to use while driving in traffic." In fact, since this is only a simple camera we're talking about, one could imagine the addition of any number of superhuman optical features: night vision, X-ray vision, microscopic focus, long-range zoom. Forget the camera even; there's no reason you couldn't jack directly into the Net. In the future, the disabled may prove more abled; we may all want their prostheses.
