The article focuses on geeks with a strong technical/computing bent. In order to understand complex systems like modern computing environments, you can't flub the details. Otherwise you end up with huge errors in your mental model at the macro level.<p>For example, A geek will know various properties of PI out to some number of decimal places etc. If they have to calculate with PI they'll try and use as much precision as possible in order for the results of the calculations to be as correct as possible at the end. A geek knows that if they just say "PI=3 is close enough". Then calculations using PI end up with all kinds of weird results...and cars will fail to roll and houses will fall down, and ballistic trajectories will miss their mark etc. So a pedantic fetishizing over the digits of PI becomes a necessity. It's hard to turn on and off that level of mental discipline, so by force of necessity most geeks simply set the switch to "on".<p>So a geek necessarily internalizes the practice of being pedantic and sweating the details.<p>This happens with anybody who sweats the details in a narrow field because they understand that you can reach the wrong conclusion at the macro level if you don't. Even in seemingly traditionally un-geeky fields like fashion or cooking, you find similar types of behavior patterns.<p>What this essay is identifying is either the lack of the ability in technical geeks to turn off the pedantic-ism or to not forcibly apply it to all aspects of life.
