Megalomaniac = narcissist + high IQ
One of these nerds is not like the others.
Notice that although it appears the megalomaniac is bored to tears with the idea of talking shop (when he could be looking at himself in the mirror), it turns out that he is a perfectly competent craftsman*. But he is first and foremost a bro and a “chad”, as I understand the term. So even if he is a nerd underneath he would rather keep that to himself because he is busy being a pussy magnet.
Something that strikes me about this type is that their body language, vocal harmonics, and word choice are exceedingly deliberate and self-conscious. According to his descriptions and the way he acts on camera now (as an old geezer), I’d expect Vox Day would have had mannerisms almost identical to this guy 20 years ago. I believe this comes from the excessive self-consciousness that comes with very high levels of mental energy and therefore willpower.
This is odd because, as a consequence of self-consciousness, high-IQ types generally tend to project less confidence and become more reserved and conservative in manner instead. But megalomaniacs appear to overcome this with aplomb, turning metacognition into salesmanship.
*I don’t know a damn thing about gear so this is actually a big guess.
