Bill Gates once said that to emulate Steve Jobs you need to be part genius and part asshole. “So many of the people who want to be like Steve have the asshole side down. What they are missing is the genius part”.
Cook is neither an asshole nor a business genius. He is a logistics genius, though.
Regardless, is there anyone remotely like Jobs right now? And I don't mean pushing up daises. The leaders I see are opinionated assholes lacking a consistent, internal drive based on strong, user-centered beliefs. (for some definition of consistent)
In today’s world, asshole-driven leadership is only going to take you so far.
