I wouldn't like to live in an environment of the kind in the video "Sight" but I do think that the level of technology in the video can be reached with the right research and technicians working on it. Given that we already have glasses that can basically do some of the things done in the video. There would simply have to be someone with great technological mind in order for them to understand what is put into google glasses and just create something as what is in the video. Also, being that they are the creator they can find a way to make a model that has power over all other created products therefore causing them to have control over everyone else.
