The wonderful Future World
It's Friday morning in the year
2025,and you're running late.You got distracted watching the music video
that as 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 magnet tells you your train which travels at speeds up to
250 miles an hour as it electromagnetically hovers above its guide
track—is a bit behind schedule,too.So you decide to drive your
environmentally-friendly hydrogen 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
instantly 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 suddenly rings.Your best
friend's face pops up on the organic light-emitting diode screen asking
what you're doing this weekend.Will you slap on your 3-D contact lenses
and play virtual soccer with the U.S.Olympic team?No,no.Your friend
says,so you have to take the new nanotube elevator (made of microscopic
fibers many times stronger than steel) 60,000 miles into space.
Could
this scene really take place in just a couple of decades?The
researchers who are currently developing all this stuff think so.These
gadgets may be as common in 20 years as cell phones and DVD players are
today.
