I'll tell you what it really is: it's banal nihilism. We have this idea that nihilism is a kind of militant anti-truth, but it mainly manifests as a lack of conviction about anything altogether. When there is no fixed truth, and your survival depends on aligning to narrative, ("getting it" as they say) the abstractions you use become divorced from anything concrete that could be interpreted as a forcing function on the perceptions of the people you are speaking to.
The article underestimates the consequences of it, and we can say "ha hah, only bullshit!" but it's much, much more pernicious than that.
Someone who is enthusiastically fluent in bullshit can be trusted to be just as enthusiastic about destroying ecosystems, livelihoods, cultures, and peers, because instead of feeling existential dread at meaninglessness, they find security in it. It's difficult for most hackers to imagine that the dim agreeable affect of a middling project manager or adjunct eating lunch at their desk as barely concealing an abyss of rage and shame - one that is only relieved by tiny acts of passive sadism, but that's literally people everywhere.
