The debate over 3D printed guns and drones has much in common, the premise of both being a loss of control to technology. Digital Tonto has some good sentences
Control Is An Illusion
In The New Digital Age, Google Chairman Eric Schmidt and his colleague Jared Cohen describe a world in which plastic guns are the least of our worries: Weaponized consumer drones, hacker-driven cyber attacks, social media enabled revolutions and a host of other technologies will undermine the rule of states.
At the same time, as the quick apprehension of the suspects in the Boston Marathon bombing showed, our means to enforce laws will increase as well. Schmidt and Cohen postulate that, in the future, attempts to avoid attention (such as a lack of an online presence) will itself be used as pretence for scrutiny.
