Changing technology stimulates (刺激) the brain and increases intelligence. But that may only be true if the technology challenges us. In a world run by intelligent machines, our lives could get a lot simpler. Would that make us less intelligent?

    After the Industrial Revolution, machines began to replace manual workers. The process played out in agriculture as well as manufacturing so that groups of agricultural workers were replaced and forced to move to cities to make a living.

    When machines took away much of the manual work, people became less physically active and gained weight. The sedentary (久坐的) lifestyle contributed to a worldwide spreading of overweight and related metabolic disorders such as heart disease, secondary diabetes and kidney disease .

    As our bodies rested, our brains were forced to work harder, however. It is much more difficult to drive through an overcrowded modern city than it is to move around in a small rural village, for instance. Modern jobs are also more complex and urgent and they require more education because employees need to process new information quickly. Even during our leisure time, our brains work harder due to greater availability of books and explosion of audiovisual media, for entertainment, study, music, news, and so forth.

    Now in the Internet age, the amount of information grows fast along with the advance of electronic technologies. The number of people with whom we interact electronically grows by leaps and bounds thanks to the ease of use of social media like Facebook and Twitter.

    All of this extra work for our brains makes us more intelligent. That helps explain why human intelligence increases steadily from generation to generation in all developed countries, a phenomenon named the Flynn Effect. Of course, there are other reasons, including improved nutrition, better medical practices that reduce brain damage, and improved sanitation and public health that reduce diseases of childhood.

    In the P.G Wodehouse novels, Bertie Wooster got away with being a fool because Jeeves was there to back him up with superior brain power. Similarly, people of the future are at risk of being less intelligent because machines will do their thinking for them.

    Artificial intelligence is taking over many human jobs. For instance, planes are being flown much of the time by automatic pilots. Moreover, the complex problem of controlling air traffic around large modern airports is also achieved by artificial intelligence that operates well beyond the capability of mere human air traffic controllers.

    Artificial intelligence exists in many fields of modern life for the simple reason that intelligent machines can already outperform humans, including some aptitudes (天资) which were once thought to be a human advantage, such as playing chess or recalling details in a game of Jeopardy.

    Machine intelligence is increasing much faster than human intelligence. As machines get smarter, they will do more of our thinking for us and make life easier.

    Instead of struggling to identify ourselves to some electronic system via passwords that are secure only if they are hard to remember, the system will work harder to identify us using biometrics (生物测定学) such as fingerprints or even the individual sound of our hearts. More technologies of the future may also be voice-activated so that we will talk with machines much as we would talk to a friend.

    In the future, the electronic assistant will develop to the point where it serves similar functions as a real living chief male servant of a house, fulfilling requests such as: “Organize a dinner party for six on Thursday, Jeeves, and invite the usual guests .”

    At that point, our long struggle with challenging technologies is at an end. Like Bertie Wooster, we can take it easy knowing that the hard work of planning and organizing is being done by a better brain—the electronic assistant. Starved of mental effort, our brains will return to an earlier or less advanced form.

    The future is still in the fog.

Electric Cars

    Where do cars get their energy from? For most cars, the answer is petrol. But some cars use electricity. These cars have special motors that get their power from large batteries.

    Most people tend to think of electric cars as a new invention, but they have been around for a long time. They were popular when the technology for petrol engines was not very advanced. Recently, electric cars have again become popular because people want cars that pollute less.

    Electric cars are better than petrol cars in several ways. The biggest benefit is reduced pollution. In areas where there is a high percentage of electric cars, there is less pollution. But it is important to understand that electric cars still cause pollution. Remember that the electricity to power electric cars has to come from somewhere, which is most likely a power station. Unless these power stations run on solar or wind energy, they are most likely burning coal and oil to make electricity. The second benefit of electric cars is a reduction in the dependence on foreign oil.

    There are several countries, including the United States, which don't want to rely on oil coming from other countries to power their transportation systems. They want the power to come from within their country, and since electric cars can run on electricity from coal or nuclear power stations, there is less of a need to import oil.

    Despite the benefits of electric cars, there are some problems with them as well. One disadvantage is that electric cars are more expensive than petrol cars. This is mostly due to the high cost of the batteries these cars need. Electric cars run on batteries, just like a mobile phone does. But unlike a mobile phone, you cannot charge your electric car's battery by plugging it into a wall. They need to be charged in special places. Now, there is a lack of places where people can charge the batteries. Another problem is that electric cars cannot travel as far as petrol cars. Some people are afraid that the battery will run out of electricity (and the car will stop) before they reach their destination.

    Despite these problems, many people, including automobile industry experts, believe that the percentage of electric cars will increase in the future.

    A few days ago I was sitting in a Thai restaurant enjoying a meal when I got a phone call from a friend I hadn't spoken to for a long time. Full of enthusiasm and excitement I talked slightly louder than usual and in Spanish, my mother tongue.

    A few minutes into the call the lady sitting beside me got up, seemingly upset, and asked the restaurant staff to relocate her to a table as far away as possible from “this man who won't get off his phone”.

    I sank in my seat out of embarrassment. I ended the call soon afterwards and felt the urge to go over and apologize. Before getting up I looked around to see where she was and I found she was, indeed, at the table furthest away from me. I noticed that the lady was alone and staring out of the window, looking a bit sad.

    Right then I quit my plan for a conventional apologetic gesture and decided to conduct an experiment. Seeing those funny smile cards in my wallet, I took one out. When signing my check I asked the waiter to secretly charge the lady's meal to my credit card instead of her bill.

    I left the restaurant, letting the waiter know I would be back in a few hours to pick up my credit card. I returned later as promised, excited to learn the result.

To my pleasant surprise, things turned out the best possible way. A group of restaurant staff approached me with joy, telling me that the lady had dined there many times, but they had never seen her smile and laugh like she did upon receiving the smile card and the $0 check.

    Welcome to the Electronic Village to explore new ways of language teaching and learning.

    We don't know how different our future will be in the future. We can only try to imagine it.

    At first we think about human relationship. 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. It will be much faster and easier for us. On the other hand, our relationships 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.

    Spending holidays will also be completely different. Traveling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will be using solar­powered 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. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in 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 optimistic about our future. We should be happy and believe good things will happen.

    Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.

    A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet (LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.

    According to Sari Nijssen, the study set out to answer the following question:" Under what circumstances would adults be willing to sacrifice robots to save human lives?" The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine.

    The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans.

    "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."
