You guys are mocking, but seriously, once quantum computers are fully operational (next 5 years) you can forget about humanity as we know it. The first program written on a quantum computer will automatically become an advanced artificial intelligence capable of anything due to quantum fluctuations(study up on quantum mechanics if you dont understand). Facebook, google, power companies, schools, political powers, banks will all be overrun by a.i and there isn’t a damn thing anyone can do about it.
