     Today, there's hardly an aspect of our life that isn't being upended (颠覆) by the tons of information

available on the hundreds of millions of sites crowding the Internet, not to mention its ability to keep us in

constant touch with each other via electronic mail. "If the automobile and aerospace technology had

exploded at the same pace as computer and information technology," says Microsoft, "a new car would

cost about $ 2 and go 600 miles on a small quantity of gas. And you could buy a Boeing 747 for the cost

of a pizza."

     Probably the biggest payoff, however, is the billions of dollars the Internet is saving companies in

producing goods and serving for the needs of their customers. Nothing like it has been seen since the

beginning of the Industrial Revolution, when power-driven machines began producing more in a day than

men could turn out in nearly a year. "We view the growth of the Internet and e-commerce as a global

trend," says Merrill Lynch, "along the lines of printing press, the telephone, the computer, and electricity."

     You would be hard pressed to name something that isn't available on the Internet. Consider: books,

health care, movie tickets, construction materials, baby clothes, stocks, cattle feed, music, electronics,

antiques, tools, real estate, toys, autographs of famous people, wine and airline tickets. And even after

you've moved on to your final resting place, there's no reason those you love can't keep in touch. A

company called FinalThoughts.com offers a place for you to store "afterlife e-mails" you can send to

Heaven with the help of a "guardian angel".

     Kids today are so computer literate that it in fact ensures the United States will remain the

unchallenged leader in cyberspace for the foreseeable (能预测的) future. Nearly all children in families

with incomes of more than $75,000 a year have home computers, according to a study by the David and

Lucile Packard Foundation. Youngsters from ages 2 to 17 at all income levels have computers, with 52% of those connected to the Internet. Most kids use computers to play games (some for 30 hours or more

a week), and many teenage girls think nothing of rushing home from school to have e-mail chats with

friends they have just left.

     What's clear is that, whether we like it or not, the Internet is an ever growing part of our lives and

there is no turning back. "The Internet is just 20% invented," says cyber pioneer Jake Winebaum. "The

last 80% is happening now."
