Just remember technology is released for use about 20years after its development. The predator drone was developed in the 80s, for example, utilizing 1960s technological advancements. I personally have worked on camera systems that you would not believe if I told you about them. The technology I have worked on while aboard the naval research lab a few years back makes those systems in your video look like atari. No joke. I did have a dream once where cameras could penetrate the ground and do facial recognition from 30,000 ft on skeletons. but it was just a dream I am sure...
