I am worried about the coming dronepocalypse.

Enjoy your clear skies while you can. When no-name manufacturers can make cheap drones which can be launched by anonymous malicious people to e.g. drop bombs on Times Square, there is no accountability. How will our systems cope with that? For the first time we'll have autonomous, cheaply made robots among us. (Self-driving cars, by contrast, are not cheap to make.)

And even without malicious intent, there will always be a 1% chance that some big drone will drop on people's heads ...
