Cook was also running Apple ops for a decade before being CEO. It's not like he appeared out of nowhere. One can argue Apple's design chops and freedom to innovate were because of Cook, who cleaned up all the business and ops shenanigans that were driving Apple bankrupt under Scully, Spindler and Amelio, and create a stable foundation for Jobs to work his magic.
I am certainly not happy with Tim Cook from a Product and Strategy perspective. But from an Operation / COO perspective. He is second to none. So good that I put him as Genius in this Category.
