Self-made billionaire Ray Dalio is no less "weird." In his book, Principles, he describes how he sees reality: "Nature is a machine. The family is a machine. The life cycle is like a machine." Dalio's company, the largest hedge fund in the world, records every conversation (meeting or phone call) inside the company and has built several custom apps that allow any employee to rate any other employee in real time. The data is then added to profiles that each employee can see and is subsequently fed into an artificial intelligence system that helps employees make better decisions.
