Jim: Science and technology is developing rapidly in modem times, changing and transforming the whole world in a radical way.
Teddy: I agree with you. It has, on the one hand, made our fives much easier, providing us with all kinds of conveniences, but on the other, also caused us trouble.
Jim: Compared with past, we have changed a lot. Many tasks that had to be done by ourselves is now been carried out by computers. As we rely more and more on technology, our ability to think and act independently is undermined.
Teddy: For simple examples. Letters are supplanted by emails. Conversations are replaced by text messages. Writing with a pen becomes a form of art, and even books are being read on a screen.
Jim: Do you remember a word said by Sydney J. Harris, "The real danger is not that computers will begin to think like men, but that men will begin to think like computers."?
Teddy: Yes. Concerns about the decline of man"s mental capacities are not unfounded. Despite all the tasks technology can help us to accomplish, it is still necessary for us to sharpen our thinking skills and make full use of our own brains.
