That is a terrible thing to say, about anybody, despite your attempt at back-tracking. Steve single-handedly made APPLE what it is today, and APPLE would have evolved with or without him. I'm glad you agree he was an enormous persona.
Incredible! Is this for real? Are there any clinical trials going on?
Sorry to say, but Jobs didn't single-handedly make Apple what it is today. He was the man at the top; he was a visionary and a great salesman. But even he knew he couldn't do it all on his own. So he surrounded himself with others who shared in his vision. Cook, Schiller, Ive, Johnson, Forstall, Rubenstein all come to mind, and deserve tremendous credit for the things they've done at Apple.
As for Tim Cook, here's my opinion.
Marketing is making people want something. Operations is being able to put it in their hands. Most people have no idea about operations and supply chain management.
Jobs knew little about operations, so he hired Cook to run operations for him. Cook knows little about marketing/ salesmanship, so he lets Schiller do most of the talking.
Still, you would be hard pressed to find a better operation than what Cook has done at Apple.
