In the human-machine relationship, you, fellow Homo sapiens, are commonly designated as the owner, operator, or otherwise dictator of the subservient device in your possession. Consider, however, the reality of your relationship with your phone. First of all, it knows everything about you. It reads all your emails, sees all your pictures, learns your favorite websites, and even remembers the unsent texts you draft in the middle of the night. It tracks where you’ve been and when, who you’ve talked to and for how long — and if you have a particularly smart new phone, it also knows your resting heart rate and level of physical activity. The jobs that NSA and KGB spies would train for decades to master are now being handled by the little computer in your pocket. In its spare time. As a sideline entertainment. And what do you know about your phone, other than the megapixels of its camera or the gigabytes of its storage?
