家园 "我的诀窍是理性": almost AI modeled

1.

巴菲特's 理性 is well demonstrated in his investment, now in retrospect: we all know he has a profound understanding of both US economy, and Chinese economy, his famous investment picks are well known.

other than 巴菲特's 理性 of so called "fundamental analysis", we now have what I called AI modeled 理性" of today's "AI 巴菲特": everybody knows that a few HFT firms in WS almost always make money by day trading, they obviously have their kinds of market 理性 modeled out;

杨振宁 is basically saying, his 相位場 can help people to connect local physics law globally, therefore we have some kind of 理性, as opposed to be a local animal only.

this is a good piece, 比尔.盖茨/沃伦.巴菲特:答商学院学生问, I like 巴菲特 part much better.
