Everything is going to change more in the next ten years than it has in the last hundred, so it’s difficult to think about 100 years in the future. To think about an indefinite future is very interesting. No one knows the world of 100 years in the future. I just guess about it; however, I think it will be better to live then than now.
After 100 years, I think that borders will disappear by the development of science and technology. In other words, the world will be united into one. By advances in transportation, people can move to other places easily, so dividing up the land is meaningless. People will move not only to other regions of the earth but also to other planets in space because the Earth is already full.
What kinds of car will we be driving in the future? We dream of a car which can move by electricity and which is clean on the environmental side. The future car will have a device on seats, which can be changed to fit adults and children instead of the current fixed ones. It won't need a driver. There will be no car crashes, because computer-controlled cars will safely find out an adequate way. What drivers will have to do is to inform the car where its destination is and then the computer can to do the rest.
The food of Mercury, Venus, Mars, and Jupiter will become popular, so many people will go to a food institute to learn about the foods of external worlds. People who don’t have time will eat such things as beans. It will contain enough nutritive value. It is easy to buy at the supermarket.
My family will live in Seoul, but I’ll take the super airplane daily to my work office. It’ll take 30 minutes from Seoul to New York. My wife will go to her office in London. We have a plan to eat dinner in Paris.
Linguists in the world will worry that their languages will disappear. Everything is connected by Internet, so many people will use English. English will be the language of all the countries in the world, so people in the world can correspond easily. Maybe English centers will disappear. We won’t have to stress about English. I'm looking forward to that happening someday.
