When the CEO of OpenAI says that he expects at least 40% of all jobs to be eliminated by 2030 by the tool that's also making personal computing -whether PC or smartphone-, video gaming, and on-prem business computing somewhere between incredibly expensive and unaffordable, and driving up the price for just about everything else substantially -because just about everything has a computer in it or depends on computer-controlled processes these days-, you don't need some boogyman theory to understand why people are angry about the thing that's making the already-rich far, far richer.
Though. blaming it on the boogyman does have the benefit that you don't actually have to address the concerns of those revolting peasants!
