Through vivid storytelling and captivating real-world characters, Wachter grapples with the urgent questions that will shape medicine’s future. How should we regulate AI technology in healthcare?

slow? Most critically, what values should AI embody, and who gets to decide? Before reading this, I wasn’t all that interested in AI; now I can’t look away.”

“A Giant Leap is a deeply researched, unflinchingly honest, and ultimately hopeful analysis of how AI will transform healthcare and the systems, cultures, incentives, and human choices that will determine whether the technology becomes a force for good or a source of new risks. We are at an inflection point in healthcare where AI is challenging us not just to adopt new tools but to reimagine care itself. Wachter is neither an AI evangelist nor a doomsayer. He is a steward, guiding us through the promise and perils with a clinician’s rigor and perspective. He has done what very few can: synthesize the technical, clinical, economic, and ethical dimensions of AI in healthcare into a story that’s urgent and accessible. It is necessary reading.”
