The future is hazardous. Technology consultant Jay Freeman discusses unlocking your Google Glass and describes what will happen when your pair is (inevitably) hacked:
Once the attacker has root on your Glass, they have much more power than if they had access to your phone or even your computer: they have control over a camera and a microphone that are attached to your head. A bugged Glass doesn’t just watch your every move: it watches everything you are looking at (intentionally or furtively) and hears everything you do. The only thing it doesn’t know are your thoughts.
It also hacks into every device you interact with. It knows all your passwords, for example, as it can watch you type them. It even manages to monitor your usage of otherwise safe, old-fashioned technology: it watches you enter door codes, it takes pictures of your keys, and it records what you write using a pen and paper.
