I can understand why people doubt the feasibility of drone delivery, especially given the legal impediments to adoption. Frankly, I doubt that this type of service will be practical within four years. What I can't understand is why people openly reject the idea of drones.
I don't see how Prime Air is any less safe or efficient than sending thousands of five-ton metal boxes barreling down residential streets. I don't see why a five-pound piece of plastic falling from the sky poses an appreciably greater risk than a branch falling on you. I don't see how people can draw parallels between small, low-altitude consumer drones and military UAVs. The level of fear surrounding this announcement makes no sense.
The response to Prime Air goes far beyond skepticism. It's incoherent, fanatical pessimism, and it's really dissapointing.
