Drones are everywhere. Their uses are almost beyond count, from the lethal, to the beneficial, to the bone-headed (think spying on a rival soccer team). They represent one of the great technological leaps forward of our time.

Drones have even made dictionaries out of date. My cherished, but yellowing, Oxford English Dictionary defines “drone” as “a male of the honey-bee. It is a non-worker.” Too true in its day — the drone was only good for mating.
