Matthew L. Jones speaks about key illiteracies surrounding metadata, the hacking of our court system, and the possibility of ethics at scale. Jones is a 2017-2018 Data & Society Fellow who studies the history of science and technology, with a focus on early modern Europe and on recent information technologies. He is completing a book on computing and state surveillance of communications and is working on a historical and ethnographic account of big data, its relation to statistics and machine learning, and its growth as a fundamental new form of technical expertise. Jones is currently a James R. Barker Professor of Contemporary Civilization at Columbia University’s Department of History.
