Apple once pushed Steve Jobs out, and paid a steep price for doing so. More recently Steve Jobs was forced to resign as CEO by a terminal illness, leaving behind a team that understood and loved him. These situations are only superficially similar.
Larry Ellison, on the other hand, has never had to deal with life without Steve since first making his acquaintance, thirty-some years ago. It is understandable that he would want to attribute the success of Apple entirely to Steve Jobs, but in doing so he discounts the possibility that Steve may actually have managed to make himself unnecessary to that success, something he was clearly aiming for in his last few years.
Apple's continuing success is a tribute to Steve's foresight and understanding of the schlock-intolerant collaborative process, which he endeavored to infuse deeply into the way Apple works.
