Peering into the 21st century, authorities on the
future see extraordinary changed. New scientific breakthroughs will allow
machines to take on more tasks that human brain has traditionally
done. Computers, which once only remembered data, will make
more decisions. Machines that today tell doctors what symptoms the patients have
may soon be recommending whether or not to perform surgery as well. Others will
design new buildings after questioning buyers about their preferences.
Increasingly, human thought processes and even values are being programmed into
computers, according to Earl Joseph, president of a consulting firm. "Imagine
machines which are smarter and more intelligent than humans and, with their
embedded (植入的) initiative, can't wait to tell you about it," he says.
In everyday life, the future will mean talking directly to computers
without pushing buttons. Just tell a toaster, stove or other kitchen device what
to do, and it will hear the message. The oven may even decide itself how long to
cook the roast. Tell the television, "I want to watch Channel 12 at 8 p.m., but
store the show for next week," and the job will be done. The
computer will talk back, too. Already some soft-drink machines complain loudly
if you don't deposit enough cash. At home, a bedside machine may someday tell
you, "You forgot to turn off the basement light." Away from
home, the automobile of the future will think for itself. Scientists predict
that drivers will feed destinations into a computer that will then explain what
route to take and even tell where parking spaces are available. A city's
traffic-control system might instruct the car's computer how fast to go in heavy
traffic and whether to change lanes.
