Yeah, I probably should have included a warning about incoming psychic damage on that link. Sorry.
Although highlighting the phrase "intelligence displacement" construct dies illuminate that the whole case they make is built on the same foundations as that other Rat fixation: eugenics and race science! Like, I'm not saying the author is definitely a eugenicist breaking out the skull calipers, but their argument is based on the same idea of what "intelligence" is in the first place. It's a distinct commodity that is produced or contained in certain minds and is the ultimate source of the value that they create. If you're a "knowledge worker" you don't provide a specific perspective, experience, expertise, or even knowledge, you just plug your intelligence into the organization like connecting a new processor bank to a server farm. Because it's disconnected from a person's individuality and subjectivity we can model it effectively as a commodity and look to optimize its production, either by automating away the squishy human element with ai or by increasing the productivity of current methods by optimizing for the ~~white~~ "right" kind of person.
I've heard worse ideas. It's funny; I would have expected the people who were in tech because it looked like the best bet for a relatively stable in-demand career would have been the ones who were crap at it relative to the folks doing it purely for love of the game. But it turns out that having something else going on is closely linked to touching grass in ways that make you harder to lure into the cult.
