John Pemberton — Diabetes Dietitian & Creator of The Glucose Never Lies
In this episode, John Pemberton — a diabetes dietitian, type 1 diabetic, and creator of The Glucose Never Lies — shares his seven-year journey from building diabetes education guides to developing Grace, an AI agent designed to deliver expert-level type 1 diabetes education tailored to each user's pace and needs.
John breaks down Grace's three-layer architecture (consensus guidelines as the source of truth, his lived clinical experience as the delivery layer, and a Nassim Taleb-inspired philosophy of black swan caution, via negativa, and skin in the game) and explains why the tool is intentionally designed to get users 80% of the way there, leaving the critical final 20% to human-to-human connection.
The conversation also dives into the messy economics of building AI in healthcare, how Grace will be funded so it stays free for patients, and a candid look at which jobs AI will reshape — and why great communicators, not information jockeys, are the currency of tomorrow's medicine.
