 Neil Stevenson recently talked about the failure of science fiction. Jules Verne excited our imaginations with 20,000 Leagues Under the Sea. He inspired not just children, but those children then grew up and many of them became scientists and engineers to go and actually go 20,000 Leagues Under the Sea and to go around the world in less than 80 days. And so Neil said, today science fiction writers are not pushing the boundaries of our imagination far enough. He said that we science fiction writers need to start pushing out the imagination. And that will then bring in the children and they might then decide we want to follow what this science fiction points out. That is, it may be possible to go to distant planets and I think it can be a catalyst for children to say, one, I'm really jazzed by this problem. I'm really jazzed to go solve this problem. Number two, I can see a pathway to actually solving it now and I see that there's other people like me and the imagination of going from this was impossible to this is climbable, this is doable. All we have to do is look at the four minute mile. Was there something in human evolution that changed in a matter of six months that caused us to say that four minute mile was impossible? Just look at his action as his long legs carry him nearer that world record. To then 50 people in a matter of two years doing the four minute mile? No, human evolution didn't change. The human body didn't change in a matter of six months. It was the imagination barrier.
