In this episode of Lifers, Christina Farr sits down with Dr. Bob Wachter, Chair of the Department of Medicine at UCSF and author of the seminal book The Digital Doctor. After years of observing the "hope, hype, and harm" of health technology, Dr. Wachter discusses his new book, A Giant Leap, and why he has moved from a skeptic to a staunch optimist regarding AI's role in medicine. They dive into the high-stakes reality of autonomous AI, the "incumbency advantage" of companies like Epic, and why the primary care crisis makes AI integration an absolute necessity.
