Everyone has been placed under a level of surveillance straight out of a dystopian science fiction novel. Spying is accomplished mostly through connected personal devices – especially, for now, smartphones – that people keep practically glued to their bodies. Data is gathered about each person’s communications, interests, movements, contact with others, emotional reactions to circumstances, facial expressions, purchases, vital signs: an ever-growing, boundless variety of data. Algorithms correlate data from each person and between people. The correlations are effectively theories about the nature of each person, and those theories are constantly measured and rated for how predictive they are. Like all well-managed theories, they improve through adaptive feedback.
