Amazon didn't go anywhere with drone delivery because for most last mole delivery peoblems drones don't make sense. Especially not at the scale of Amazon. Sure, drones are great for really fast point-to-point deliveries, especially in remote areas. And that is not a problem Amazon, or any other company like UPS or DHL, has to solve. Another business Amazon retired, but a ton of start-ups still think is a good idea, is groccery deliveries.
