【简答题】
The belief that new technologies are causing the death of work is the idea that never goes away. Despite evidence to the contrary, we still view technological change today as being more rapid and dramatic in its consequences for work than ever before. But this is nothing new. People have always viewed the technological change that takes place during their lives as the most dramatic and dangerous that ever happened in history. In the 1930s, the British economist John Maynard Keynes predicted the widespread use of electricity would produce a world where people spend most of their time doing nothing. In the United States during the 1960s, the government repeatedly investigated fears that automatic machines would permanently reduce the amount of work available. In 1988, one Australian historian claimed that at least a quarter of the workforce would be without jobs within 10 years because of computers. Of course, none of these disasters came to pass in the United Kingdom, the United States and Australia, or anywhere else. Yet today, we are seeing the return of these predictions, with some experts claiming the world of work is once more undergoing radical and unprecedented change. They argue that robots and other workplace technologies are causing a reduction in the total amount of work available, or are bringing a more rapid pace of substitution of machines for humans than the one that has been seen previously. But there is a little evidence to support such beliefs. Statistics show that the percentage of people in work, the number of hours they work, and how frequently they change jobs have remained remarkably constant over the past 20 years. This stability should not come as a surprise. There are good reasons why we should not expect new technologies to cause the death of work. New technologies always cause job losses, but that is only part of the story. What also needs to be understood is how they increase the amount of work available. One way this happens is through the increases in incomes that accompany the use of new technologies. With the introduction of these technologies, goods and services can be produced faster, which results in higher real incomes for workers. Higher incomes then increase demand for other products and consequently more workers are needed to make them. Additionally, while new technologies are likely to substitute for some types of workers, they will also increase demand for other types of workers, especially those with higher - level skills and expertise. So, the end of work is no closer today than at any time in the past. But there is still a need to keep disproving the predictions and to reduce people's fears.
