Cook will be a disaster. He would have been fine as an exact opposite but balancing weight against a visionary leader like Jobs, as Ives would have been. But as the visionary leader, a man whose only contributions have been to reduce costs and quality in order to increase profits, it's going to go down a predictable path that other companies have followed.
The salary and $385 million signing bonus thing being reported are obscene for Cook who has not a single case of innovation, because it is something he is simply not capable of. This is not an insult against him, it is a simple acknowledgment of his known strengths and capabilities.
