Futuristic much?

Imagine in the future:

We don't have to turn any buttons for the TV, we just said what channels we want.

We don't have to drive at all! All cars equipped with GPS computer and we just said the exact place we want to go then the car bring us to it. (That would avoid accident I guess coz teh computer is driving for us!)

There are less traffic light. (Because I'm sick of stopping at red lights)

Laptops can be put in our pockets and handbags!

Internet is always very fast.

We will never have to go to school again because we all a personal computer robot as a teacher at home! we're actually home-schooled again.

If these happens.....
WE ALL WILL TURN FAT AND LAZY AND WE WILL BE STUPID

Seriously.
Fat because we don't use our muscle much. And of course that makes us lazy.
Stupid because we won't have to think a lot to do complicated things in the world!
