LMAO, this is now old tech. Neurosky has had braincontrolled headset since 2005, Google Glass has been out since 2012, extoskeleton has been around for years, etc.,.  Haha, Google+ and nametag have searchable face database. 

This so called future tech in these videos are for people living disconnected from the modern society/city. Half of it is open-source or at least the alternatives are.
