We've all been making some big choices, consciously or not, as advancing technology has transformed the real and virtual worlds. That phone in your pocket, the surveillance camera on the corner: You've traded away a bit of anonymity, of autonomy, for the usefulness of one, the protection of the other.
Many of these trade-offs were clearly worthwhile. But now the stakes are rising and the choices are growing more fraught. Is it O.K., for example, for an insurance company to ask you to wear a tracker to monitor whether you're getting enough exercise, and set your rates accordingly? Would it concern you if police detectives felt free to collect your DNA from a discarded coffee cup, and to share your genetic code? What if your employer demanded access to all your digital activity, so that it could run that data through an algorithm to judge whether you're trustworthy?
