Nothing says cool less than solving a Rubik's cube in fewer than 20 seconds. But there is no doubt that among tech nerds they have their own concept of cool: the cool tech nerd is hyper-intelligent, fluent in mathematics, a programming whiz with fantastic manual dexterity. Although these qualities typically express themselves in a blur of insectoid activity that appears the opposite of a Fonz's laid back disinvolture, in fact they are equivalent when considered relative to their immediate environments. The slow and steady ratiocination of a Fonz is more deliberate, better considered and more appropriate than the clueless flapping of his beta acolytes when faced with a novel problem, just as, when confronted with the need to quickly code up a casino-breaking app, the response of the alpha nerd is a flurry of fingers and machine-gun commentary rather than the bovine incomprehension and rabbit-in-the-headlights stasis of any normie onlooker.
To rephrase: the alpha cool normie shows their mastery of the situation through appropriately minimal activity, whereas the alpha cool nerd does the same but for a different type of situation and through appropriately maximal activity.
