Tina White is a doctoral student in mechanical engineering at Stanford, a self-described libertarian, and the head of a group called Covid Watch, a new nonprofit that released the first ever open-source protocol for a voluntary app that uses anonymous, decentralized data to give all of us more information about the disease that has shuttered the global economy. She talks to Nick Gillespie about all that and her libertarian beliefs.
