The Computer Moves In
By the millions, it is beeping its way into offices, schools and homes
WILL SOMEONE PLEASE TELL ME, the bright red advertisement asks in mock irritation, WHAT A PERSONAL COMPUTER CAN DO? The ad provides not merely an answer, but 100 of them. A personal computer, it says, can send letters at the speed of light, diagnose a sick poodle, custom-tailor an insurance program in minutes, test recipes for beer.
As the Apple Computer advertisement indicates, the enduring American love affairs with the automobile and the television set are now being transformed into a giddy passion for the personal computer. This passion is partly fad, partly a sense of how life could be made better, partly a gigantic sales campaign.
The sales figures are awesome and will become more so. In 1980 some two dozen firms sold 724,000 personal computers for $1.8 billion. When the final figures are in for 1982, according to Dataquest, a California research firm, more than 100 companies will probably have sold 2.8 million units for $4.9 billion. Estimates for the number of personal computers in use by the end of the century run as high as 80 million. The "information revolution" that futurists have long predicted has arrived, bringing with it the promise of dramatic changes in the way people live and work, perhaps even in the way they think. America will never be the same.
The most visible aspect of the computer revolution, the video game, is its least significant. But even if the buzz and clang of the arcades is largely a teen-age fad, doomed to go the way of Rubik's Cube and the Hula Hoop, it is nonetheless a remarkable phenomenon. About 20 corporations are selling some 250 different game cassettes for roughly $2 billion this year. According to some estimates, more han half of all the personal computers bought for home use are devoted mainly to games.
More than half of all employed Americans now earn their living not by producing things but as "knowledge workers," exchanging various kinds of information, and the personal computer stands ready to change how all of them do their jobs.
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 desktop 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.
The 1,450 data bases that now exist in the U.S. range from general information services like the Source, a Reader's Digest subsidiary in McLean, Va., which can provide stock prices, airline schedules or movie reviews, to more specialized services like the American Medical Association's AMA/NET, to real esoterica like the Hughes Rotary Rig Report. Fees vary from $300 an hour to less than $10.
