I absolutely believe bullshit jobs are threatened by AI, I'm just skeptical about simulations being produced by pro-business private schools that have every incentive to flatter their corporate sponsors. MIT has received over two hundred million dollars of investments from IBM for AI research and is seeking an additional billion dollars to build out its AI campus. They're beneficiaries of the bubble.
They have a lot of incentives to lie, here. It sounds like they just built a simulation to tell them what they wanted to hear.
