Until recently, if an item was small, remote-controlled, had a propeller and flew, then it was a toy… And probably a crappy one at that.
Now quadcopter drones are performing all manner of nifty precision tricks. Make no mistake, these tricks are a precursor to a coming technological revolution. The results of this revolution are unknown, but they will have huge implications for law enforcement, military, journalism, cinematography, and scientific research.
As with any new technology, some of the applications will be incredibly beneficial to human life, and other will be destructive. Drones can rapidly travel where humans cannot to gather data, or make repairs. Drones can also be used for surveillance and murder.
Regardless of their application, you can expect to see drones playing a larger role in our lives over the coming years.
