I, Cringely The Final Frontier :

“For all but the last century man has functioned strictly in two dimensions, traveling the earth and seas but only marveling at the air. Invention of the airplane changed that a little, yet today less than a quarter of a percent of Americans know how to fly. What if we all could fly? A decade from now we just might.
Technology exists today for people to fly by themselves, quickly, quietly, with little or no pollution, from anywhere to anywhere in any weather, asleep or awake, because the real pilot is a computer. A decade from now, thanks to Mooreʼs Law, this technology will be the price of a car.
What would the world be like if you did not need a road or even a driveway? How would demographics change? Would our crumbling infrastructure still need repair?
Meet George Jetson. He has an electric aerial vehicle that takes him where he needs to go. But he does not fly it; the vehicle flies itself, knowing to the centimeter where it is anywhere on earth, lighting like a dandelion fluff with thirty thousand other such fluffs over a major city, each going its own way yet aware of all the others. This is where transportation is headed.”
