Re: Drone delivery - again?

That's a secondary problem. The primary problem is seeing the food arrive at the destination: If you live/work on an upper floor of a building you have no chance to get food from a drone (or robot), period.
Even if you can open a window (which you usually can't in modern office buildings), there is no way a huge-ish contraption with a substantial number of fragile turning propellers can get close enough to hand over your order safely. It only works if you have a large lawn and a butler who can go get the parcel for you.
And I'm not even mentioning the pilot and autonomy problems. Because the drone won't fly alone, nor will it cover any big distances, especially carrying a heavy load. It's just a publicity stunt.
