The Computer Revolution

img The computer has been the defining technology of the current era. Together with supporting technologies such as miniaturized digital electronics and communications, it has radically transformed most areas of lifemedia, commerce, research, industry, education, entertainment, health care, the military, and day-to-day living. It has also revolutionized thought about fundamental concepts about what it is to be human, such as the nature of intelligence, the fabric of information, the structure of society, the legacies of culture, and the nature of work. Prognosticators suggest that even more profound changes lie ahead. This section reviews research and artistic activity focused on the past, present, and future of computers. For many, the computer is an appliance sitting on desks. But computers actually have much wider reach, and researchers are feverishly working to extend their application into every corner of life. Invisible computers lurk everywherein the toaster, the toy, the automobile, the television, the stove. Computers underlie many systems that people rely ontelephones, manufacturing, transportation, health care, finance, and government. Even more profoundly, digital information systems have changed cultural patterns, for example, in the ways people are abstracted and represented, the ways social decisions are made, the ways we attribute value to information, and the ways that images are used to shape meaning.
