For all I know he might even be right about introversion. What I'm bothered about is that he makes a blanket statement about "the programmer". Would've been better to say, Graham was probably introvert, there's where his ideas come from. Why would "ability to create and inhabit a mental utopia devoid of the complications of external reality is a truly liberating experience" be limited to introvert programmers, like introversion is some kind of super power? Architects, painters, mathematicians, and many others are just as capable of abstract thought. Most mathematical and physical models could be called "mental utopias". As are financial or economic models for that matter. No one would claim that because an architect is able to draw a house made of ice cream cones or a physicist come up with a model where frictions is 0 he must be introverted though right? Why does everything concerned with programming need to be then? It's similar to claiming that programmers are good at programming because they're white, or male, or fat, or bald... And people thinking they know everything are common in every field, mechanical engineers, doctors, architects, you can find them wherever you go, this is not limited to software engineering.
