Most of the people in this documentary are important figures in the history of computer science, such as Lawrence Roberts, Bert Sutherland, Robert Kahn and J.C.R. Licklider. There are developments predicted in the film that have actually come into existence a generation later, such as the electronic banking item. The film is also notable as a sort of anthropological record of the clothes and hair of the subjects. Also all the treeware all over the desks is amusing, in hindsight.
