Aside from the delivery in 30 minutes, for me the coolest part is delivery to the back of your garden. You can get secure deliveries, even while not at home. That's great.
I guess you'll have a 2-3 year secure-delivery-to-your-garden window.
Build a drone that tracks other drones going out of the Amazon warehouse, wait until parcel is dropped, and pick it up.
You could of course build a drone-police which shuts down all dark-drones. I hope the costs of such an infrastructure will be paid by taxes on drone delivery (or by increased price in drone delivery), and that society at large is not left covering the cost of such nonsense.
I imagine the packages dropped off at the backyard will be even more secure than that.
- is it worth it?
- will I get caught?
- am I a robber?
Stealing from the front of your house does not happen because most people are not robbers, and it is easy to get caught. Besides, you don't know what's inside, so you don't know if it's worth it.
A criminal operation with a dark-drone infrastructure is a different issue altogether:
- difficult to get caught, at least until we create structures to fight such operations
- it is organized by thieves - by definition
- it does not matter what you are stealing: once you have the dark-drones working, operating them is very cheap, so you can steal as much as you can, making the operations profitable.
I think that depends a great deal on where you live. Nice small town in the country where everyone knows each other, no problems, big city, no chance of it not being stolen.
In Italy the express couriers are not allowed to leave stuff in your front yard, and it's generally not possible to schedule the first delivery attempt.
