It's not technology problem but execution problem. The 5 lbs/20 mi drones are quite feasible in wide urban areas to pre-selected customers. FAA is no longer a problem. It's all about deploy to small group, iterate and expand. But team there seems to be taking extra-ordinarily cautious approach until everything gets perfect - which it probably never will. Typically you don't see media to follow up on 5 year old promises of a CEO so this could very well might be hit piece generated by some insider. Anyway, I suppose Paul Viola's days there are numbered now. It's surprised they survived this long under Bezos without delivering anything at all.
