Will life in the future be better, worse or the same as now? Futurologists（未来学家）predict that life will probably be very different in 2050.
First of all, it seems that TV channels will have disappeared by 2050. A computer will send the program directly to the television. On TV screen appear holograms（全息图）, which are pictures with certain height, width and depth. We will be able to see, smell and touch the things that we see on television.
Water has become one of our most serious problems. Agriculture is changing and people are growing more fruit and vegetables to export. Demand for water will increase ten times in 2050. Some futurologists predict that water will be the cause of war if we don’t act now.
In transport, cars will run on new fuels and go very fast. A car will have computers to control its speed and there won’t be any accidents. On the other hand, space planes will take people around the earth in about three hours. People will fly from Los Angeles to Tokyo by space plane in just half an hour.
In the field of technology, robots will have replaced people in factories. By 2050, we will see robots everywhere. They do not ask for pay rises or go on strike, and they work 24 hours a day. 
Medicine technology will have conquered many diseases by 2050; we will be able to help blind and deaf people see again and hear again. Scientists have discovered how to control genes. They have already produced clones of animals and will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. If you want all this to come true, you should study science and technology hard.

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!
For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant 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 manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened?  Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. 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.
Why? The technology worked fine, but it over—looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower?  Probably not---it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.
