Pleasure.

What will it be tomorrow? Could it be that we don't need to go to school at all? Could it be that, at the point in time when you need to know something, you can find out in two minutes? Could it be -- a devastating question, a question that was framed for me by Nicholas Negroponte -- could it be that we are heading towards or maybe in a future where knowing is obsolete? But that's terrible. We are homo sapiens. Knowing, that's what distinguishes us from the apes. But look at it this way. It took nature 100 million years to make the ape stand up and become Homo sapiens. It took us only 10,000 to make knowing obsolete. What an achievement that is. But we have to integrate that into our own future.

Encouragement seems to be the key. If you look at Kuppam, if you look at all of the experiments that I did, it was simply saying, "Wow," saluting learning.

There is evidence from neuroscience. The reptilian part of our brain, which sits in the center of our brain, when it's threatened, it shuts down everything else, it shuts down the prefrontal cortex, the parts which learn, it shuts all of that down. Punishment and examinations are seen as threats. We take our children, we make them shut their brains down, and then we say, "Perform." Why did they create a system like that? Because it was needed. There was an age in the Age of Empires when you needed those people who can survive under threat. When you're standing in a trench all alone, if you could have survived, you're okay, you've passed. If you didn't, you failed. But the Age of Empires is gone. What happens to creativity in our age? We need to shift that balance back from threat to pleasure.
