"I don't have the slightest interest in gold. I like understanding what works and what doesn't in human systems. To me that's not optional; that's a moral obligation. If you're capable of understanding the world, you have a moral obligation to become rational. And I don't see how you become rational hoarding gold. Even if it works, you're a jerk." - Charlie Munger
