They will all be linked by the information superhighway.
Researchers call it 'ubiquitous computing'.
To shave your electric bills, the system might keep your water heater turned off until it sensed you were waking up. Your morning paper, either printed or on a paperlike screen, might focus on stories of special interest to you. Your car might be driven automatically by a central traffic controller, or the controller might suggest routes for avoiding slowdowns. You could easily work at home, setting a computer pad to show you video images of your co-workers. Another pad might show your spouse or children as they went through the day.
