1 . Life will probably be very different in 2050. First of all, it seems that TV channels will have vanished by 2050. Instead, people will choose a programme from a “menu” and a computer will send the programme directly to the television. By 2050, music, films, programmes, newspapers and books will come to us in the similar way.

In many places, agriculture is developing quickly and people are growing fruit and vegetables for export. This uses a lot of water. Therefore, there could be serious shortages of water. Some scientist predict that water could be the cause of wars if we don’t act now.

In the future, cars will run on new, clean fuels (燃料) and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Also, by 2050, space planes will fly people from Los Angeles to Tokyo in just two hours.

Some big companies now prefer to use robots that do not ask for pay rises or go on strike, and work 24 hours a day. They are also easy to control. And they never argue with people. They can be easily used in a variety of places — factories, schools, offices, hospitals, shops and homes.

Scientists will have discovered how to control genes (基因). Scientists have already produced clones (克隆) of animals. By 2050, scientists will be able to produce clones of people and decide how they look and how they behave. Scientists will be able to do these things, but should they?

2 . When I was a boy growing up in New Jersey in the 1960s, we had a milkman delivering milk to our doorstep. His name was Mr. Basille. He wore a white cap and drove a white truck. As a 5-year-old boy, I couldn’t take my eyes off the coin changer fixed to his belt. He noticed this one day during a delivery and gave me a quarter out of his coin changer.

Of course, he delivered more than milk. There was cheese, eggs and so on. If we needed to change our order, my mother would pen a note — “Please add a bottle of buttermilk next delivery” — and place it in the box along with the empty bottles. And then, the buttermilk would magically (魔术般) appear.

All of this was about more than convenience. There existed a close relationship between families and their milkmen. Mr. Basille even had a key to our house, for those times when it was so cold outside that we put the box indoors, so that the milk wouldn’t freeze. And I remember Mr. Basille from time to time taking a break at our kitchen table, having a cup of tea and telling stories about his delivery.

There is sadly no home milk delivery today. Big companies allowed the production of cheaper milk, thus making it difficult for milkmen to compete. Besides, milk is for sale everywhere, and it may just not have been practical to have a delivery service.

Recently, an old milk box in the countryside I saw brought back my childhood memories. I took it home and planted it on the back porch (门廊) . Every so often my son’s friends will ask what it is. So I start telling stories of my boyhood, and of the milkman who brought us friendship along with his milk.

4 . 2050 seems a long way away, but it is not impossible to predict the future though. With the speed we are moving now so many amazing things are going to happen in the future. So where is technology going in the future?     1    .

◇The Internet will be free for everyone.

The Internet is really a key driver these days. But it is not free for everyone yet. There have already been attempts like Facebook’s Free Basics.     2    , there is a very strong possibility that the Internet will be free for everyone in the future.

◇Personal airplanes will be used widely for short journeys.

With the increasing population, it is not very hard to predict that common methods of transportation will not be enough.     3    , so in this case personal airplanes will be a handy method of transportation for common people. Of course, there will be proper air traffic control for these personal airplanes.

◇Most cancers will be treated successfully.

    4    . It will be a huge achievement in the history of medical science. Many studies are already showing a trend (趋势) towards this.

◇    5     .

There will be great achievements in space research. In the year 2050, humans will be able to live on Mars. We will receive more intelligent signals from space. Chances are we will be able to find the next Earth — like planet.

6 . Given how valuable intelligence and automation are, we will continue to improve our technology if we are at all able to. At a certain point, we will build machines that are smarter than we are. Once we have machines that are smarter than we are, they will begin to improve themselves. The concern is really that we will build machines that are much more competent than we are. And the slightest divergence (分歧) between their goals and our own could destroy us.

Just think about how we relate to ants. We don’t hate them. We don’t go out of our way to harm them. In fact, sometimes we take pains not to harm them. We step over them on the sidewalk. But whenever their presence seriously conflicts with one of our goals, we will kill them without hesitation. The concern is that we will one day build machines that, whether they’re conscious or not, could treat us with similar disregard.

The bare fact is that we will continue to improve our intelligent machines. We have problems that we desperately need to solve. So we will do this, if we can. The train is already out of the station, and there’s no brake to pull. If we build machines that are more intelligent than we are, they will very likely develop in ways that we can’t imagine, and transcend us in ways that we can’t imagine.

So imagine we hit upon a design of super intelligent AI that has no safety concerns. This machine would be the perfect labor-saving device. It can design the machine that can build the machine which can do any physical work, powered by sunlight, more or less for the cost of raw materials. So we’re talking bout the end of human labour. We’re also talking about the end of most intellectual work. So what would apes like ourselves do in these circumstances?

But the moment we admit that information processing is the source of intelligence, we have to admit that we are in the process of building some sort of god. Now would be a good time to make sure it’s a god we can live with.

7 . It’s 2035. You have a job, a family and you’re about 40 years old! Welcome to your future life.

Getting ready for work, you pause in front of the   mirror. “Turn red,” you say. Your shirt changes from   sky blue to deep red.Tiny preprogrammed electronics   (智能电子元件) are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe you’re 40. You look much younger. With amazing advances in medicine, people in your generation may live   to be 150 years old. You’re not even middle­aged!

As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear, “To lose weight, you shouldn’t eat that!” from your shoes. They read the tiny electronic code(电子源码) on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?”A list of possible foods appears on the counter as the kitchen checks its food supplies.

“Ready for your trip to space?” you ask your son and daughter. In 2015 only specially trained astronauts went into space—and very few of them. Today anyone can go to space for day trips or longer vacations. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor says you need   these   for   space   travel.” Thanks to medical advances, vaccination shots (防疫针) are a thing of the past. Ordinary foods contain special vaccines. With the strawberries in their mouths, the kids head for the front door.

It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot,”you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e­newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.

8 . 2050 seems a long way away, but it is not impossible to predict the future though. With the speed we are moving now so many amazing things are going to happen in the future.    1    ? Let’s start our predictions.

◆The Internet will be free for everyone.

The Internet is really a key driver these days. But it is not free for everyone yet. There have already been attempts like Facebook’s Free Basics.    2    , there is a very strong possibility that the Internet will be free for everyone in the future.

◆    3    

With the increasing population, it is not very hard to predict that common methods of transportation will not be enough. There will be much heavier traffic on the road. So in this case personal airplanes will be a handy method of transportation for common people.

Of course, there will be proper air traffic control for these personal airplanes.

◆Most cancers will be treated successfully.

    4    . It will be a huge achievement in the history of medical science. Many studies are already showing a trend towards this.

◆Humans will live on other planets.

There will be great achievements in space research. In the year 2050, humans will be able to live on Mars. We will receive more intelligent signals from space.    5    .

10 . With the rapid development of science and technology, we don’t know how different our life will be in the future.     1    .

At first we think about human relationships. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet — even our husbands or wives will be met in this way.     2    . On the other hand, our relationship with people won’t be as important as they are today — we will feel a little lonely.

Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.

    3     . Traveling to other planets or to the moon will also be available for everyone. Means of transport will, of course, change, too. We will be using solar-powered cars, which will be much more environmentally friendly.

We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true.     4    . And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in a better condition.

Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather confident about our future.     5    .
