Take Gates: When Allen was still around, Microsoft was a still a small company IBM was still laughing at. Then Allen left. Gates, it was JUST Gates, went on to build Windows 3, Office, Windows 95, Windows 98, Windows NT, IE, Windows Server, SQL Server, Windows XP, and more. Gates grew his fortune from a few hundred million dollars to $50 billion or so. That growth was due to Gates. Period. And that was the significant growth that blew the doors off IBM, Sun, HP, Lotus, etc. Got it now?
For Jobs, you are really working to be brain-dead: What Woz and Jobs did with the Apple II, etc. is nearly irrelevant to what Jobs did at Next, Pixar, and after his return to Apple. Apple became for a while the most valuable company in the world due to what Jobs did, Jobs, JUST Jobs, with Woz watching from the nickel seats. Sculley? Amelio? They just helped show how bright Jobs was.
For your "would have never made it to where they got", we have no way to know that.
You are illustrating a huge point that I did make: People like to fight. Even over something really obvious, people like to fight. If you and I were cofounders, then no matter what I did and no matter what success the company was having, you'd be fighting me every way you could think of, fighting, fighting, fighting, for no good reason except you just want to be fighting. There's no way you could be effective.
