The rise of drones (unmanned aerial vehicles) has been at the forefront of the news over the last months, with issues emerging that range from the remote use of military force to domestic privacy.
However there are many very positive applications of drones. Matternet, spawned from a Singularity University program, envisages creating a network of drones to address developing world problems. Over a billion people are geographically isolated and are often not able to access regular transport and the goods that can travel to them. Rather than building physical infrastructure, drones can cheaply and easily allow drugs, food, and other essentials to get to where they are needed. The video below shows the Matternet Vision.
