Why not?Im sure the richest man in the world has thought about the future.The end piece is the delivery and at the moment it’s people in the gig economy driving around in their own vans dropping off.This is only going to start off in one area.Before the covid we never saw electric scooters now they are everywhere.
You're thinking of the problem rather then the solution.
Do you know much about drones? I'm not an expert either but I used to work with a guy who had the full CAA licence and even then he lost a few drones from simple malfunctions.
Now imagine a drone falling out of the sky on a busy motorway or other road. You might say that they will plot the drone route to avoid busy streets but it will STILL have to fly over a lot of streets just to get to a customer's house.
Where will it take off from? The Amazon warehouses? There's not all that many of them which creates a problem for flight range and flight path i.e. almost inevitable the drone will fly over heavy traffic areas.
Even if you avoid heavy traffic areas completely.....big IF.....then how can you prevent the drone being caught by a strong cross wind or bird strike or any other number of factors?
How many parcels do you think the drone is going to being flying around with? It's not financially viable if it can only deliver one parcel at a time compared to a delivery driver and if it's carrying multiple parcels at the same time then how the f*ck is it going to separate the right parcel from the remaining parcels at the point of delivery.
The whole idea is fanciful.
