By almost any measure, Tim Cook has been one of the best tech CEOs ever. He diversified product lines, launched new lines of business, expanded across the globe, and grew Apple's overall market value ten-fold.
Cook is the rare public tech figure who has, for the most part, survived the vagaries of a public life. Did he disappoint many when he appeared to bend the knee before the United States' divisive President? Absolutely, though if you understand Cook, and you listen to his explanations, you know why he did it and how it actually fits into his worldview. Generally, though, Cook's been on a 15-year-long winning streak that was made possible by both sticking to the strict ethos of Steve Jobs' original Apple charter and by pragmatically doing things his own way.
