Have you ever considered what an important part work plays in our general lifestyle? For most of us, our jobs are the main things that motivate and direct us, and around which we organize our lives. Perhaps this stress on work began with our Puritan forefathers, who believed that the best way to serve God was through honest hard work, or perhaps our fundamental belief in work stems from a time when this country was young and we needed people who believed in hard work to carry out the arduous business of pioneering. Whatever the reason, it is undeniable that work is important to us. Think about the situation that arises when you meet someone and try to learn more about him or her. An early question is very frequently something such as, 'What do you do?' or 'Where do you work?' this kind of question usually follows 'What's your name?' and is now so common with us that we do not stop to wonder why we ask it. But, you know, it is very possible that in the future the question will disappear, and we might very well ask instead, 'What do you play?' Computers and other technological, equipment are making jobs more automated and less personally demanding. Scientists tell us that one day in the foreseeable future, very few people will have to work. Our society will be operated by computers and we will have much more free time, so that our games will become more important than our jobs. At the beginning of this century, almost everybody believed in work. But by the end of this century, we might be thinking quite differently. Today, people are divided into social classes in accordance with the types of work they do tomorrow, it is more than likely that we will be divided according to the types of games we play. This change in the use of our time may give rise to a new race of therapists (治疗学家) called 'fun specialists,' who will fill the same functions as our current career specialists. They will show us how to get the most fun and enjoyment out of our leisure time. Someday people will no longer be known primarily by the work they do. What is the main idea of the passage?
