The productivity paradox is finally breaking. For decades, digitizing healthcare forced doctors to become high-paid data entry clerks, spending eight hours a week on “pajama time” filling out charts at home. The system was so sclerotic it remained the country’s largest user of fax machines long after drug dealers abandoned pagers.
Dr. Bob Wachter argues the first real win is the ambient scribe. On Freakonomics Radio, he described tools that record patient visits and synthesize notes, letting doctors at places like UCSF look patients in the eye again. Generative AI can now summarize a 600-page medical history in 30 seconds, catching a 20-year-old diagnostic error buried on page 397. It’s a wingman that satisfies both clinician sanity and hospital billing.
The real shift is diagnostic. Dr. Pierre Elias developed EchoNet, an AI that scans cheap, routine EKGs for hidden signs of structural heart disease. In a trial, elite cardiologists identified disease 64% of the time - barely better than a coin flip. The AI hit 78%. It doesn’t think like a doctor; it finds mathematical patterns in electrical activity that are literally invisible to the human eye. Elias cited a patient misdiagnosed with asthma whom the AI flagged for severe heart failure, leading to a life-saving transplant.
“The promise of AI ‘co-pilots’ carries a significant psychological risk: the atrophy of human expertise.”

The breakthrough carries a trap. Wachter pointed to a Lancet study where gastroenterologists using AI to spot lesions during colonoscopies saw their accuracy improve - but when the AI was switched off, their performance plummeted below their original baseline. He calls it a potential “death spiral” where leaning on the digital crutch erodes the very clinical reasoning skills needed if the system fails.
Regulation is another hurdle. Wachter contends agencies like the FDA, built for static drugs and devices, aren’t fit for software that updates daily. He argues for a light touch to avoid stifling innovation, noting that professional conservatism and malpractice fear are stronger guardrails than any government rule.
The system is too broken to just hire more humans. Wachter’s optimism is rooted in that dysfunction. But success hinges on culture and workflow, not just code. The race is on to integrate AI without triggering the deskilling it’s meant to cure.
