Stuart W. Elliott, research fellow at Carnegie Mellon University, investigated the potential for commercial computers to replicate human work skills in the coming decades. Drawing on the latest research in computer science and analyses of occupational skill levels, Elliott assessed the implications of computerized labor for economic production and employment. Will computers compete only with lesser skilled workers, and if so, what portion of the current labor force would they displace? How would the productivity of higher skilled workers be affected? Elliott also explored the likelihood that computers can be made to perform at increasingly higher levels across all fields of human employment.
