Summary
Overview
Dr. Zand and Dr. Chris explore the opportunities and risks of using AI chatbots for medical advice. With expert Dr. Emma Caroon from the Alan Turing Institute, they examine how these large language models work, their limitations including hallucinations and lack of regulation, and establish guidelines for safe use. The episode emphasizes treating AI as a powerful tool requiring the same scrutiny as medical devices, not as a replacement for healthcare professionals.
Introduction to AI in Healthcare
The hosts introduce the episode by discussing Chris using a chatbot to diagnose his creaky knee, setting up the central question of whether AI can reliably provide medical advice. They establish that while AI chatbots are becoming ubiquitous and feel intelligent, there are significant concerns about their trustworthiness and appropriate use. The conversation frames AI as a powerful new tool that requires careful examination before widespread adoption for health purposes.
- Chris demonstrates using a chatbot to get advice about his creaky knee, receiving seemingly helpful suggestions about rest, ice, and exercises
- AI chatbots are being used throughout medicine - in clinics, for recording consultations, diagnosing cancer, reading scans, and drug design
- Despite medical professionals using AI, patients need to employ caution with unanswered questions about trust and risk
" I'm just asking my chatbot about my knee. My knee is creaking again. What should I do? "
What Are AI Chatbots and How Do They Work
Dr. Emma Caroon explains that artificial intelligence has existed for 70 years, but generative AI represents a recent breakthrough in conversational capability. These chatbots are trained on over a trillion words from the internet - including books, websites, social media, and YouTube videos. Importantly, they function as sophisticated summarization tools rather than thinking entities, presenting information in digestible formats without true reasoning or intelligence.
- Generative AI is distinct from traditional AI due to its massive scale and human-like conversational ability
- Popular chatbots like Gemini, Claude, and ChatGPT are trained on over a trillion words from publicly available internet content
- Medical journals are often behind paywalls, so general AI models may not have access to the most current research
- AI chatbots are essentially advanced summarization tools, not thinking entities - they present data conversationally without true reasoning
" It's over a trillion words it's actually trained on. How much is a trillion words? Well, what's available on the internet. "
