What is the most life-changing technology of your generation?

The Internet. This one seems like a no-brainer, but the Net’s unique strength is that no two people will agree on why it’s so important. The world’s largest and most unruly library, it’s also a global news channel, social club, research archive, shopping service, town hall, and multimedia kiosk. Add to that the most affordable mass medium ever, and a curse to anyone with a secret to keep. Three-fifths of Americans now use the Net, but it remains to be seen whether the connections to one another will transform us, or prove that we’ll never change.
