The thing is that AI is a catch all term and the AI used in medicine has little to do with chat bots or generative AI in general.
It's not that GPT-10 will cure cancer when asked for it. But neural networks are good at pattern recognition so cancer detection is a promising application for example. Also, personalizing a cure is also an idea. It's not that we need a super intelligence and curing cancer is the excuse for data centers for scam bots. Medical AI is no excuse for generative AI.
