Look at electricity in human history - it took a few decades for electricity to really revolutionize the American economy. And the Internet will be the same. At some point in the future, we will arrive at a new era of low-hanging fruit.

When you look at the actual data on technological innovation, one thing you see is that what I call the 'low-hanging fruit' has been exhausted. So radio, flush toilets, electricity, and automobiles - a lot of very basic inventions - have spread to almost all households.
