Interesting book about the “start” of quant trading by Jim Simons. Funny he was a strong smoker and quick sharp and active till the end, great Mathematician and was code breaker! I didnt know anything about Renaissance. In part, it reminds me the book from Edward O. Thorp. It was weird that with so much tech and algorithms developed, in key moments, he didnt trust them. Reminds me to Nassim Taleb and the dark swans. Still he was never crashed and always made money. I always feel uneasy with this subject. Is it moral? The thing that surprise the most was the connections with Donald Trump by members of his company and Brexit election. But he supports and finance Democrats.
