Futurists love computers. After all, 40 years ago electronic digital computers didn't exist today microchips (微型集成电路片) as tiny as a baby's fingernail are making all sorts of tasks faster and easier. Surely the future hold still more miracles. Some of the computer experiments now going inspire imagination of the future. For example, scientists are working in devices that can electronically perform. some sight and hearing functions, which could make easier for the blind and deaf. They are also working on artificial arms and legs that respond to the electric impulses (脉冲) produced by the human brain. Scientists hope that someday a person who has lost an arm could still have near-normal brain control over an artificial arm. Video games, computerized effects in movies, and real-life training machines now being used by the U. S. Army are causing some people to predict new educational uses for computers. Computers could someday be used to imitate travel to other planets, to explore the ocean floor or to look inside an atom. Experiment with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals (终端) . Cars, too, might be equipped with computers to help drivers find their way around or to communicate with home and office computers. Many people, including handicapped (残废的) workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work—they'll just turn on a terminal. Which of the following would be the most appropriate title for the passage?
