## Summary

In this thought-provoking conversation, surgeon Shafi Ahmed and digital health futurist John Nosta revisit Geoffrey Hinton’s bold 2016 prediction that radiologists would soon be replaced by AI.

🔍 Topics covered:

Why AI hasn’t replaced radiologists yet—and what’s holding it back
The role of large language models in diagnostics and clinical practice
The debate over accuracy, intuition, and the “art” of medicine
Accountability and liability when AI makes mistakes in healthcare
The deeper question: is AI truly intelligent, or does it think in a way fundamentally different from humans?

💡 Shafi and John don’t always agree—but together they explore the future of medicine, the limits of technology, and the ethical, clinical, and philosophical challenges that will define healthcare in the AI era.
