I mostly agree with you, though you should be also opened to the possibility that not even Jobs would be able to do with Apple in the next 10 years what He did in the past 10 years.
And not only that, I feel like it should be accepted that Jobs was able to really accomplish things at the level at which he did _because_ of the others helping behind the scenes.
No one else could have done what Jobs did with Apple in the past 10 years. No one else will be able to do it in the next 10 years.
Replacing one multi-talented genius with five talented geniuses does not produce the same result.
