What's next for drones

These developments raise a number of questions: Are drones safe enough to be flown in dense neighborhoods and cities? Is it a violation of people's privacy for police to fly drones overhead at an event or protest? Who decides what level of drone autonomy is acceptable in a war zone? Those questions are no longer hypothetical. Advancements in drone technology and sensors, falling prices, and easing regulations are making drones cheaper, faster, and more capable than ever.
