 And what's interesting is that 300 years ago, there might have been 500 million people on planet Earth. There are 8 billion of us. And generally, we're all living better. There's maybe 5% to 10% of the people who are not who are still living the way that we lived 300 years ago. And that's a tragedy. But they can do better. And they will do better if they get the right ideas. If you study history, what you see is that ideas shape history, not, well, human nature. That's what we do. We kill each other. No, we don't. We don't have to. We do, but we don't have to. And the question always is, will we rise to the challenge?
