It’s Friday morning in the year 2030, and you’re running late. You got carried away watching the music video that was playing in the corner of your bathroom mirror while you were brushing your teeth. How will you get to your office at Mega Giga Industries on time?

    A quick check of your Internet–connected refrigerator tells you your train is a bit behind schedule, too. So you decide to drive your environmentally–friendly fuel cell car instead—or rather, let your car drive you. It’s programmed to know the way and it will get you there without speeding, getting lost, or crashing.

   Settling into your office chair, which changes color to match what you’re wearing, you pick up yesterday morning’s newspaper. Printed on reusable electronic paper, it immediately rewrites itself with today’s headlines. Now it’s time for your big meeting. Uh-oh! You’ve left your handwritten notes at home. No problem. The digital ink pen you used has stored an electronic copy of what you wrote.

   Your wristwatch videophone (可视电话) suddenly rings. Your best friend’s face pops up on the screen (屏幕) asking what you’re doing this weekend. Will you play virtual soccer with the U.S. Olympic team? No, no. Your friend says, so you have to take the new elevator (made of microscopic fibers many times stronger than steel) 60000 miles into space.

    Could this scene really take place in just twenty years? The researchers who are now developing all this stuff think so. These gadgets (小器械) may be as common in 20 years as cell phones and DVD players are today.
