Yeah it's a fad that once people get over the initial WOW factor they won't use again.
In this country some retailers do same day home delivery, in some cases it's more expensive than the item you've bought and nobody uses the service now, but last year when the service was first introduced, everybody was doing it.
It's also my understanding that these drones are 99.9% autonomous, and in many cases there will not be a 1:1 operator, they rely on GPS co-ordinates and sensors for flight, it was a loophole a guy in our club noticed about the UK regulations, I.e. There was nothing covering fully autonomous drones flying themselves on waypoint missions, basically once launched you could set the model to fly autonomously anywhere and it not require a pilot or observer while in autonomous mode lol
It's why I wouldn't be surprised if the drone has laser scanned mapping on it from google maps or whatnot for flight and the service will probably only be available in areas that have been fully mapped previously, much like how in the uk autonomous cars are only going to be allowed onto motorways at first, and then that's only after every square inch of our motorway network has been mapped and laser scanned.
