Apple and Google have generated much hope and controversy with their plan to create a Covid-19 tracking app. Too bad it won’t work.

Public debate has focused on how to balance the right to privacy with the potential to save lives. There’s ample reason for skepticism -- for example, “anonymous” Bluetooth tracking can be deanonymized. But that’s not what I care about. What concerns me is that the whole concept of a tradeoff is false from the start, because no app can fix the thoroughly inequitable U.S. health care system.
