Philip Agre earned his PhD in 1989 in computer science, but his greatest impact came when he left the technical side of the field and helped create the field of social informatics, or the study of how technology and humanity interact. Then he disappeared, leaving behind a legacy of work that was eerily prescient in predicting how technology would impact society.
