Life in 2100

Recently, there was an article in the Week magazine that shared what life will be like in the year 2100, according to the world's top 300 scientists.  It was fascinating and worth mentioning:
-The Internet will be in your contact lenses.  Just think..you are wondering through Roman ruins and you'll be able to see the rise of the Roman Empire at the same time.  Talk about multi-tasking. it's a librarian's dream-always having information in their eyesight.
-Cars will be driverless, using GPS to navigate without the help of an alert human behind the wheel.  Wow. No more DD's. Car trips will be a breeze.  In fact, cars will be able to fly. Traffic and accidents are a thing of the past. And best of all, you barely need to fuel up-there's no friction to slow us down. Energy crisis solved.
-Doctors can grow spare body parts. No more organ donors needed.
-Toilets and bathroom mirrors will contain DNA sensors, capable of detecting proteins and emitted from perhaps a hundred cancer cells in a cancer colony, 10 years before a tumor forms.  A medical checkup every time we use the bathroom.
-Tourists will soar into outer space via a space elevator.  IF you are wealthy.
So right now, my concern is to download a short story on my PC, figure out my mother's mp3 player, and change my phone's ring tone. Where's my robot??  Guess its all relative...
