Gray sheds light on the workers—many of them women caring for young children and elders—who support the technology industry and the lack of regulations governing their labor. Mary L. Gray, senior principal researcher at Microsoft Research, 2020 MacArthur fellow, and coauthor of the book Ghost Work, discusses what governments and the technology industry can do to address this emerging fault line of inequality.
