All-powerful Computer: Potential applications of the computer made possible by microelectronics include a small computer in every home or a pocket computer terminal that can be connected to a powerful central computer via the telephone. Such devices may be used to solve our numerical problems (e.g., income tax, or our bank balance) or as a creative tool to relate our knowledge and experiences to our future actions.
But Johannesson is not primarily a science fiction writer; he is, under his pseudonymous mask, a well-known Swedish astronomer. He is moderate in his writing, whereas Harlan Ellison, one of the angriest of the current crop of angry young science fiction writers, is not. In his 1967 short story, "I Have No Mouth and I Must Scream," Ellison's man of the future also succumbs—and all but disappears—in the face of the all-powerful computer. A few humans are kept alive, however, so that the computer may ingeniously and endlessly torture them for its own amusement.See Also A Computer Causes:a computer causesnd wha computer causest of the computer?

On The Other Hand See Complex Computer:Every electronic instrument, however, whether a TV receiver or a complex computer, must have an input and an output device that "connects" with the outside world. In the TV re¬ceiver, for example, the input is the antenna and the output is the picture tube. For the computer, the input device may be a typewriter or a magnetic tape, while the output may be sheets of paper printed by a typewriter, or a TV-like picture on a cathode ray tube.
What are the essential technological tools that make this progress in education feasible? Consider an example: Each school could have a reliable, relatively low-cost information-handling system, or computer, that can store and manipulate enormous quantities of information. A large number of students would be able to communicate simultaneously with the central computer through individual terminals that would include a visual display device, such as a television picture tube, on which each student could view words, numbers, and pictorial information retrieved from the computer's memory store. The student might use a typewriterlike device to "converse" with the computer and to respond to the problems that he views on the display screen. |
