In the next ten years we will see data-driven tech­nolo­gies recon­fig­ure sys­tems in many dif­fer­ent sec­tors, from autonomous vehi­cles to per­son­al­ized learn­ing, pre­dic­tive polic­ing, to pre­ci­sion med­i­cine. While the advances that we will see will cre­ate phe­nom­e­nal new oppor­tu­ni­ties, they will also cre­ate new challenges—and new worries—and it behooves us to start grap­pling with these issues now so that we can build healthy sociotech­ni­cal systems.
