It is a lot easier to write an essay critique than it is to sit down and fix the problem by recording your own set of video lectures that teach people what you know.
Yep. You would need a) an iPhone app that you would use to place your order (it would send updated coordinates as you move around, and provide a perimeter within which you would have to stay) b) an army of quadcopters so that a subset of them could be charging while the others were making deliveries c) the quadcopters would have to be equipped with parachutes in case they malfunctioned so they wouldn't kill someone on the way down. d) The quadcopters would have to keep a persistent connection with the central server through wireless networks to keep in sync with your latest position and to send back their coordinates for you to see on your phone. e) there would have to be a mechanism in place to prevent mid-air collisions (buildings you could pre-encode, birds and other quadcopters you couldn`t) for bonus points, you generalize the whole thing and make it like an airbnb where people can exchange arbitrary goods and you just broker the deal and execute the deliveries for a fee that would be dynamically calculated based on distance and weight. DO IT. DO IT NOW.
