Passage five Today，there’s scarcelyan aspect of our life that isn’t being upended by thetorrent of information available on the hundreds of millions of sites crowdingthe Internet, not to mention its ability to keep us in constant touch with eachother via electronic mail. “If the automobile andaerospace technology had exploded at the same pace as computer and informationtechnology，” says Microsoft，“anew car would cost about $ 2 and go 600 miles on a thimbleful of gas. And youcould buy a Boeing 747 for the cost of a pizza. Probably the biggest payoff, however, isthe billions of dollars the Internet is saving companies in producing goods andserving for the needs of their customers. Nothing like it has been seen sincethe beginning of the Industrial Revolution, when power-driven machines beganproducing more in a day than men could turn out in nearly a year. “We view the growth ofthe Internet and e-commerce as a global megatrend，”says Merrill Lynch，“along the lines of printing press,the telephone, the computer, and electricity. You would be hard pressed to namesomething that isn’t available on the Internet. Consider: books, health care, movietickets, 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 movedon to your final resting place，there’s no reason those you love can’t keep intouch. A company called FinalThoughts. com offers a place for you to store “afterlife e-mails” you can send to Heavenwith the help of a “guardian angel”. Kids today are so computer savvy that itvirtually ensures the United States will remain the unchallenged leader incyberspace for the foreseeable future. Nearly all children in families withincomes of more than $ 75,000 a year have home computers, according to a studyby the David and Lucile Packard Foundation. Youngsters from ages 2 to 17 at allincome levels have computers, with 52% of those connected to the Internet. Mostkids use computers to play games (some for 30 hours or more a week) , and manyteenage girls think nothing of rushing home from school to have e-mail chatswith friends they have just left. What’s clear is that, whether we like it or not, the Internet is an evergrowing part of our lives and there is no turning back. “The Internet is just 20% invented，” sayscyber pioneer Jake Winebaum. “The last 80% is happeningnow. “
