I think Apple is a perfect example for this, with Jobs having been the visionary and Cook the guy who implements these visions.
Horowitz stated that a company works only well with the visionary at the top. We can see how true this as Cook just is not creative. I am sure he works really hard and is really smart but he should have never gotten to where he is now. At first I thought he would only be a interim solution to manage Apple while they search for another creative genius but that seems not to be the case.
