Abstract :
In last year???s January tech issue, I focused on the disturbing threat to privacy that unmanned aircraft seemed to pose. Who, after all, would want to be stalked by a small, camera-toting drone that was recording their every move? Seems I got that one wrong. Plenty of people??? sports enthusiasts in particular???are ravenous for selfies taken by aerial robots. And start-ups everywhere are now scrambling to develop this technology for them.
