Information is bad for knowledge.

We know from chaos theory that even if you had a perfect model of the world, you'd need infinite precision in order to predict future events. With sociopolitical or economic phenomena, we don't have anything like that.

An elephant is vastly more efficient, metabolically, than a mouse. It's the same for a megacity as opposed to a village. But an elephant can break a leg very easily, whereas you can toss a mouse out of a window and it'll be fine. Size makes you fragile.

A washing machine needs constant maintenance. It doesn't want any harm. It wants tranquility, and you need someone to - you're not going to harm it by continuously monitoring it and adjusting it.

The Internet allows the small guy a global marketplace. But technology is harmful in the sense that we get too much information from it. Because of the web we get 10 times the amount of noise we ever got, which makes harmful fallacies far more likely.

I remind myself of Einstein's remark that common sense is nothing but a collection of misconceptions acquired by age 18.

We should probably stop trading derivatives, anything more complex than regular options ... I am an options trader, and I don't understand options. How do you want a regulator to understand them?
