Harvey Castro · DR GPT™ · Five TEDx talks
Watch Harvey Castro’s five TEDx talks on healthcare AI, human judgment and the future of medicine. Each talk below includes its main idea and the audiences it may suit, so organizers can assess a related session for their event.
TEDxSouthlake
This talk connects satellites, edge computing, and AI as a real time medical nervous system. The central idea is simple and powerful: distance should not decide whether someone can reach care when time matters.
TEDxBabsonCollege
This talk focuses on timing in healthcare. Too often diagnosis and action happen after the window for prevention has narrowed. Harvey explains how responsible AI can help leaders move earlier without losing clinical accountability.
TEDxAWC
Drawing from emergency medicine, personal story, and technology, this talk shows how AI, edge computing, and biosensors can help predict serious health events before they become emergencies.
TEDxWarrenton
This talk addresses the healthcare workforce shortage and the role AI can play in making medical information easier to understand, improving diagnosis, and making care more compassionate and accessible.
TEDxPurdueU
This talk explains how AI is changing diagnosis, personalized care, and the way clinicians solve difficult problems. It is a useful introduction for audiences trying to understand the practical future of medicine.
Healthcare AI is not just a technology story. It is a leadership story, a trust story, and a clinical judgment story. If your healthcare organization, university, medical conference, pharma team, or executive group needs a keynote that is practical, credible, and human centered, bring DR GPT™ to the conversation.
Book Harvey Castro MD, DR GPT™Five TEDx stages, four states and one common thread. Every one of these talks was written by a physician who was on shift that month, which is the reason they land differently than a technology talk about medicine.
Distance is a clinical variable. When a patient is far from care, or care is far from a specialist, the delay itself becomes part of the diagnosis. This talk argues that satellites, edge computing and AI can work together the way a nervous system does, sensing at the periphery and deciding fast, so that expertise arrives before the window closes.
Best for audiences working on rural access, telehealth, or distributed care models.
One safer decision does not stay one decision. It changes the next handoff, the next discharge, the next readmission. This talk follows that ripple outward from a single early intervention, and makes the case that responsible AI is not a brake on progress but the thing that lets the ripple travel.
Best for audiences building governance, safety, or quality programs.
By the time someone reaches my department, the interesting part is usually over. The failure happened weeks earlier and nobody saw it. This talk is about moving the clinical attention upstream, using biosensors, edge computing and prediction to catch the drift while it is still cheap to fix, and about what human judgment still has to do once the signal arrives.
Best for audiences focused on prevention, healthspan, or population health.
The debate keeps getting framed as replacement, and that framing is wrong on both ends. This talk lays out the partnership version instead: where the machine is genuinely better, where the clinician is, and what a patient is actually asking for when they want a person in the room.
Best for mixed clinical and public audiences, and for opening a program.
Hard problems in medicine often are not solved by more data. They get solved when somebody changes where they are standing. This talk works through diagnosis, personalization and the problems that resist both, and shows how a shift in frame does more than a shift in tooling.
Best for university, innovation and general-interest audiences.
Not because of the count. A TEDx stage is a specific discipline: no slides to hide behind, a hard time limit, and one idea that has to survive being said out loud to strangers. Doing that five times means the material has been pressure-tested in front of five different rooms.
It also tells you something useful about fit. Look at which of the five your audience would sit forward for, and that is close to the keynote you should book.
If you want the full version of any of these for your program, that is the conversation. Most conferences end up somewhere between two of them, tailored to what their people are actually deciding this year.
