The points in your OP were already dismissed with logic. Don’t mistake people insulting you for trying to argue with you.
As for your point about OS/2, regardless of why it failed, you haven’t really supplied any evidence that it was smarties who administered badly. Accepting for the sake of argument that OS/2 was technically superior to Win95, and accepting as well that it only failed because IBM didn’t support it, it still does not follow that smarties administered badly. The smarties would be the programmers, who created a great product. The bad administrators would be other people at IBM, who didn’t support it. Thus, there is no apparent correlation, positive or negative, between intelligence and administrative ability.
Your points about Cecil have been thoroughly disproved, unless you think that somehow the failure to create the world’s fastest database server solely to run this message board, without spending any significant amount of money, is an administrative failure. And you continually show that the inclusion of yourself as a smartie is absurd.
Rewriting your question, to avoid asserting nonsense, “Why are smarties such as Cecil and myself such bad administrators, despite the lack of any evidence of Cecil being a bad administrator, or me being a smartie?”
Answer: Smarties are not necessarily bad administrators, witness Robert Oppenheimer, who administrated the scientists of the Manhattan Project, and was a brilliant physicist. However, someone who is recognized as smart due to proficiency in something other that administration (many of the other scientists there, who were more brilliant in their fields than Oppy) will not be as good as an administrator as someone recognized as a good administrator, but not incredibly brilliant otherwise (Gen. Leslie Groves, the officer who oversaw the entire Manhattan Project, and prior to that got the Pentagon built ahead of schedule and under budget).
In sort, there was once a question as to why the conductor of an orchestra got paid the most, and the answer given was that it’s because he’s the one that gets 150 egomaniacs to play as one. Or to put it simply, if writing good software or being good at calculus qualifies someone as a smartie, so should being able to administer well.
