It's possible that this is true generally, but it disproportionately affects legal, peaceful paths to power. Knowledge work is definitely not the only means to secure wealth or power through intelligence, but crucially, it is the one that currently hits the sweet spot of plausibly securing wealth and sanctioned and legal in a peaceful society. It's possible "AI" or some other technology that's been invented recently or is currently being invented closes all paths to shifts in power, but if the hype about replacing knowledge workers is to be believed, it will certainly closes the peaceful paths considerably faster, and this seems pretty bad for everyone
