What's next?

I was thinking yesterday and I realized something: my parents grew up with the automobile, the first generation to know them from the start. My generation was the second to have cars around all the time and the first to grow up with the television. Our kids were the second generation of TV and the first to grow up with the personal computer. Their kids will be the second computer generation, but what will they grow up with that their parents did not and had to learn later in life? What is the next big thing? What will come along and change the world as much as the car, the TV, and the personal computer?Hm, maybe it is already here.
