Emergency physician and AI futurist Harvey Castro MD explores how personal tragedy and triumph—his father’s fatal heart attack and his mother’s life-saving early cancer detection—sparked a mission to transform care. Drawing on frontline ER insights, he demonstrates how AI, edge computing, and real-time biosensors now predict cardiac events days ahead and spot tumors at their earliest, most treatable stage. Through compelling case studies, the talk shows that prevention is no longer theoretical—it’s happening today and can be made accessible to all. Castro ultimately challenges audiences to help build an equitable, proactive health system where people move from merely surviving to truly thriving.
