He's not talking about all tech people here. He's talking about a narrow subset:

> a certain kind of tech enthusiast, particularly the ones who are most interested in startups and entrepreneurship.

I'm sure she thinks she's not talking about all tech people, but she began the article with an anecdote about an acquaintance of hers, describing how it was "mortifying" to listen to him talk about his ideas and directly contrasting him with a "regular human" (who of course would be familiar with Swiss linguist Ferdinand de Saussure).

I don't want to overindex on the one anecdote, because I recognize this is a pretty hostile interpretation, and I could just as easily read it as playful ribbing if the rest of the article were consistent with that perspective. It's kinda not, though.
