China's history is marked by thousands of years of world-changing innovations: from the compass and gunpowder to acupuncture and the printing press. No one should be surprised that China has re-emerged as an economic superpower.
Science, as illustrated by the printing press, the telegraph, the railway, is a double-edged sword. At the same moment that it puts an enormous power in the hands of the good man, it also offers an equal advantage to the evil disposed.
What gunpowder did for war the printing press has done for the mind.
You can't have an industrial revolution, you can't have democracies, you can't have populations who can govern themselves until you have literacy. The printing press simply unlocked literacy.
Would the Protestant Reformation have happened without the printing press? Would the American Revolution have happened without pamphlets? Probably not. But neither printing presses nor pamphlets were the heroes of reform and revolution.
Our printing press is the Internet. Our coffee houses are social networks.
In one sense, the Internet is like the discovery of the printing press, only it's very different. The printing press gave us access to recorded knowledge. The Internet gives us access, not just to knowledge, but to the intelligence contained in people's crania, access to the intelligence of people on a global basis.
Humans have always used our intelligence and creativity to improve our existence. After all, we invented the wheel, discovered how to make fire, invented the printing press and found a vaccine for polio.
Over the last few millennia we've invented a series of technologies - from the alphabet to the scroll to the codex, the printing press, photography, the computer, the smartphone - that have made it progressively easier and easier for us to externalize our memories, for us to essentially outsource this fundamental human capacity.
When we developed written language, we significantly increased our functional memory and our ability to share insights and knowledge across time and space. The same thing happened with the invention of the printing press, the telegraph, and the radio.
