The truth is almost every mode of transport is selfish. It's always selfish, until everyone starts using it, at which point it's revolutionary.
Everything looks bad in hindsight right? But it is the car that enabled the progression that makes the car impractical.
I wish Mr Bezos would focus on something of real value- asteroid mining and transferal of polluting industries off-world.
The drones have no driver (thus lower margins and/or a richer Amazon, neither of which are necessarily good for inequality, though it does free up more humanity from mundane tasks like delivering parcels), and can be loaded quickly and automatically. The article mentions they can carry 5 lbs, which I suspect is enough to carry a few deliveries at once. As the article mentions, 80% of their sales are less than 5 lbs.
All that said, the noise pollution is going to be horrendous. The visual pollution I don't mind so much, as it _may_ allow cities to lower the number of cars on the road (fewer people driving to run errands), though it's definitely going to feel creepy and dystopian, especially if Amazon are the only ones running these things and there isn't _extremely_ strong privacy oversight.
40,000 people are killed every year in the US by ground-based transport.
Drones can't go that far. They can only carry tiny payloads. They use a ton of energy just to hover. And lastly- they are much more dangerous than ground-based transport, for the simple reason that _they can fall from the sky_.
Whats to be gained by putting deliveries in the air?
