According to Japan Science and Technology Agency, young Japanese are surrounded by hightech devices(設(shè)備 ), but are not interested in how they work. Japanese businesses have succeeded partly because they’ve a great many engineers. A drop in interest could lead to a decline(減少) in their numbers and quality. In the past, the young had a big interest in science and technology, said Hirano, director of the agency’s policy department. There are two main reasons for the problem. The first is known as black box syndrome of modern technology. Electronic devices depend on tiny silicon chips(芯片) , which can only be made in big factories, whose workings can’t be seen by the eyes. The devices, unlike machines of the past driven by gears and wheels, are simply boxes. Young Japanese, brought up on video games and at home with puters, enjoy using modern technology, but this is a passive interest and different from the interest in how things work. You need an active interest to get interested in science. This is declining in the young, said Hirano. About twothirds of Japanese in their 20s use PCs, twice the number of those in their 50s. But only 40% of those in their 20s say they are interested in news about science and technology, pared to 60% of the 50 to 60 year olds. Another reason for it is that life in modern Japan is too fortable, he said. A wealthy society reduces people’s desire to modernize and develop their country. To a degree, you can’t avoid this when the fruits of science and technology are fully developed. Similarly, science in Europe and the US has also suffered a lack of interest. 32.
