Computer - Man of the YearIn 1982, The Man of the Year in Time magazine was a non-human for the first time. A computer received the honour as 1982's “greatest influence for good or evil.” The article recognized that, “By itself, the personal computer is a machine with formidable capabilities for tabulating, modeling or recording. Those capabilities can be multiplied almost indefinitely by plugging it into a network of other computers. This is generally done by attaching a desk-top model to a telephone line (two-way cables and earth satellites are coming increasingly into use). One can then dial an electronic data base, which not only provides all manner of information but also collects and transmits messages: electronic mail.” |
