“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour(跑酷).
Close your eyes and imagine you are living in the next two centuries or more. You'll be living in a world filled with smart robots, which will be helping you to take care of your children, or your elderly parents in your home. You'll live much longer thanks to the medicine made by genetic (基因的) science. And mankind may be going farther in space than ever before-you will be living on the moon or Mars.
How should we view the changes that wait for us in the future? Should we be optimistic (乐观的)about the years ahead, or worried about what the future holds? Some scientists and experts are having a discussion about how technology, science and society will develop in the future.
"I'm looking forward to the day when more technology will come to my life," says John Searle, a professor at the University of California Berkeley Philosophy, "because I think further research in such areas as genetics, physics, chemistry and medicine will help us to overcome poverty, improve health, and make life longer."
Hugh Herr, at MIT's Biomechatronics Group, considers very powerful weapons as concern over the future. Another is the growing role of technology in our lives."Machines’ taking over what humans do is not a good thing," Herr says.
That is a similar concern shared by Daniela Cerqui, a social and cultural scientist. "I am afraid that the long-term future we are building will have no space left for human beings," says Cerqui. "The main values of our society are related to information that must progress as quickly as possible, and computers are much better than humans in these tasks ."
