The world ain't only vertical, hierarchical. It's a lot horizontal too. Complex feedbacks. I still clean potentially unwanted files on my desktop, Even if I have the latest architecture available on the market. True. The method (Mathematical / Empirical intuition) is a must have. As so many things are in trading. We can build algorithm, program. But we can creat programmers, mathematicians, traders ... And we can't say that the body is inferior to the mind. Well ... We can wish it is. Or think it is. But it isn't. Lol. Hierarchy goes away with meditation.
