Without the wheel, we would most likely have remained in small family groups. Limiting our exposure to other cultures. This would have made us more paranoid and probably led to many more wars.
There is not doubt that without the wheel, our progression would have been severely retarded.
We've gone beyond the capacity of the human mind to an extraordinary degree. And by the way, that's one of the reasons that I'm not interested in the debate about I.Q., about whether some groups have higher I.Q.s that other groups. It's completely irrelevant. What's relevant to a society is how well people are communicating their ideas, and how well they're cooperating, not how clever their individuals are.
So we've created something called the collective brain. We're just the nodes in the network. We're the neurons in this brain. It's the interchange of ideas, the meeting and mating of ideas between them, that is causing technological progress, incrementally, bit by bit.
