Healthcare has long resisted the forces of digital disruption that have transformed nearly every other industry. Until now. In A Giant Leap, physician and thought leader Robert Wachter chronicles medicine's AI awakening. Drawing on painstaking research and interviews with more than 100 pioneers at the intersection of medicine, technology, policy, and business, Wachter describes how AI can now match-and sometimes surpass-physicians in areas ranging from diagnosis to empathy. Even as AI enters hospitals and clinics to assist with documentation, recommend treatments, interpret images, and guide surgeries, challenges remain-including hallucinations, biases, and misinformation. Yet, Wachter argues, in a healthcare system buckling under the weight of medical errors, limited access, maddening paperwork, clinician burnout, and crushing costs, AI doesn't have to be flawless to be useful-it just needs to be better. And, if we make the right choices, it will be. Blending clinical insight, vivid storytelling, and journalistic precision, A Giant Leap is a timeless and engaging guide to how AI is changing what it means to heal and be healed in this age of astonishing technology.
