It seems we have a sort of Cantillon Effect in wages (spilling over from IT down into HVAC and food service), but not in goods.

And I'm not sure the AI/LLM focus sheds any light at all on the situation. Unfortunately, AI/LLMs aren't AGI and they're just a tool. They're just a better machine (assuming it all pans out) that radiologists all need to become experts in using. The way to analyze the situation isn't that the radiologists are the "bottleneck", the radiologists are the experts who are trained to use the tools.
