3D needs a trained eye. It can't be done by everybody. People who just do 3D just for the sake of commercializing their movie another five or six percent and they don't know really how to do it, they should care how to do it better by bringing other directors and collaborators into their lives to help teach and instruct how you really make a 3D movie because it's not just like putting a new lens on a camera and forgetting it. It takes a lot of very careful consideration. It will change your approach to where you put the cameras. So, 3D isn't for everybody.
Certain countries long ago succeeded where the U.S. has failed in commercializing their air traffic control systems, putting them in the hands of private or quasi-private operators able to raise capital, charge fees, and invest in growth, free of meddling by congressional pork barons. You want a drone-friendly air traffic control system? This is the place to start. Our FAA isn't blindly anti-drone but simply marooned in a system that still needs thousands of eyeballs gazing at radar terminals and out of cockpit windshields.
