Responding to Cory Doctorow's claims about AI diminishing labor power, Stanford radiology expert Curt Langlotz clarified the actual impact of AI on radiologists.

Even if AI could draft reports containing all findings for human review, it would only save about 20% of the time per case, making the scenario of a single radiologist overseeing nine AIs unrealistic. He emphasized that radiologists' labor power remains strong, with an average salary of around $500K in the U.S.
