In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
Not all past predictions have been proven wrong. A few of them have been surprisingly accurate. Some great thinkers predicted the arrival of the credit card,the fax machine and even
the Internet—years before they happened. But for each prediction that has come true, some others have missed by a mile. Many of these predictions didn't consider how people would like to use the technology. Or if people really needed it in their lives or not. Let's look at some predictions from the nottoodistant past.
Robot Helpers
Where's the robot in my kitchen? Nowhere, of course. And he's probably not coming anytime soon. Robots do exist today,but mostly in factories and other working environments.
Back in the 1950s, however, people said that by now personal robots would be in most people's home.
So why hasn't happened? Maybe because robots are still too expensive and clumsy (笨拙的). And probably the idea of robots cooking our dinners and washing our
clothes is just too strange. At home we seem to be doing fine without them.
Telephones of tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn't caught_on yet.
