The reptilian annual World Economic Forum at Davos, where the masters of the universe meet to congratulate themselves on their benevolent dictatorship, is home to many sinister ideas. This year, one of the creepiest discussions of all was delivered under the guise of progress and productivity. Nita Farahany, a Duke University professor and futurist, gave a presentation at Davos about neurotechnology that is creating "brain transparency." The new technologies, which Farahany says are being deployed in workplaces around the world ... include a variety of wearable sensors that read the brain's electrical impulses and can show how fatigued you are, whether you're focused on the task at hand or if your attention is wandering. According to Farahany, thousands of companies have hooked workers ranging from train drivers to miners up to these devices already, in the name of workplace safety. But what we are really discussing is workplace surveillance. Farahany paints a picture of a near future in which every office worker could be fitted with a small wearable that would constantly record brain activity, creating an omnipotent record of your thoughts, attention and energy that the boss could study at leisure. Farahany acknowledges that there could be drawbacks here: "Done poorly, it could become the most oppressive technology we've ever introduced on a wide scale." All of this raises the question: what exactly is your employer buying when they give you a paycheck? For bosses, the answer is simple: "Everything."
