"Unmanned aerial vehicles have populated both the imagination and nightmares of people around the world in recent years. In April, the United States Navy announced an experimental program called LOCUST (Low-Cost UAV Swarming Technology), which officials promise will “autonomously overwhelm an adversary” and thus “provide Sailors and Marines a decisive tactical advantage.” With a name and a mission like that – and given the spotty ethical track record of drone warfare – it is little wonder that many are queasy about the continued proliferation of flying robots.
But the industrial use of the lower sky is here to stay. More than three million humans are in the air daily. Every large human settlement on our planet is connected to another by air transport. Cargo drones will grow into an even larger industry in the coming years, simply because, unencumbered by the weight of humans and their life-support systems, they will fly more cheaply but be just as fast and safe." via Project Syndicate
