No juniors, no experts?

In the US, Stanford found that since late 2022, employment in AI-exposed jobs like software and customer support fell 16% relatively for 22-25 year-olds. Employment for older workers in the same jobs stayed steady. Matt Beane at UCSB saw this happen in robotic surgery even before AI. Surgeons used to train the next batch of residents.
