Even if the assertion is correct (which I believe to be the case), the most probable reality-based outcome is that decision makers will continue to push toward automation. If some significant portion of the humans doing the job can be replaced by LLM, or by much cheaper humans augmented by LLM, they will be so replaced. By the time it creates a real problem, those folks will have cashed out and moved on. That isn't new behavior, but folks who fall back to that as a way of dismissing concerns lack a good grasp of the scale enabled by technology, here. "Interesting times".
