      The knowledge society will be a highly competitive one, for organizations and individuals alike.

      Information technology, although only one of many new features of the next society, is already

having one hugely important effect: it is allowing knowledge to spread near-instantly , and making

it accessible to everyone. Given the ease and speed at which information travels, every institution

in the knowledge society-not only businesses, but also schools, universities, hospitals and increasingly

government agencies too-has to be globally competitive, even though most organizations will continue

to be local in their activities and in their markets. This is because the Internet will keep customers

everywhere informed on what is available anywhere in the world, and at what price.

      This new knowledge economy will rely heavily on knowledge workers. At present, this term is

widely used to describe people with considerable theoretical knowledge and learning :doctors,

lawyers, teachers, accountants chemical engineers. But the most striking growth will be in “knowledge

technologists”: computer technicians, software designers, analysts in clinical labs, manufacturing

technologists, paralegals. These people are as much manual（体力劳动)workers and they are

knowledge workers; in fact, they usually spend far more time working with their hands than with

their brains, but their manual work is based on a substantial amount of theoretical knowledge which

can be acquired only through formal education ,not through an apprenticeship（学徒期). They

are not, as a rule, much better paid than traditional skilled workers, but they see themselves as

"professionals”, just as unskilled manual workers in manufacturing were the dominant social and

political force in the 21th century, knowledge technologists are likely to become the dominant

social-and perhaps also political-force over the next decades.
