There are a number of interesting science fictional or dystopian extrapolations to be made from the new PrimeAir system currently being tested by Amazon.
For example, suppose it could be hacked by people with their own agenda?
Imagine those with illicit deliveries to make - drugs, illegal software, controlled data, it doesn’t really matter. They set up a system whereby their customers order something small from Amazon - perhaps the specific item itself ordered would be a code for the illicit item - and from a rooftop near the Amazon distribution centre their own systems watch the departures.
When they spot the right one they launch a micro-drone of their own which will rendezvous with the Amazon drone mid air and fasten something to it or drop its payload into the Amazon drone’s “bucket”.
Of course Amazon would respond by making its drones smarter and able to defend themselves. Naturally, the hijackers would respond in kind.
Thus would begin the delivery drone wars, an arms race which would result in the skies filling up with increasingly smart and sneaky machines trying to outfox each other…
