Exactly this. Reminds me of the old IBM mandate: A computer can never be held accountable, therefore a computer must never make a management decision. Clearly we are failing

The AI industry wants you to say "the AI just did that thing on its own!" Like, United Health's AI that's denying a shitload of claims with a 90% error rate? They wanted you to think it's just the AI.

🧪 An RCT of 848 caregivers in Japan found an AI chatbot boosted HPV vaccine literacy over government leaflets, but it didn't budge vaccination decisions at two weeks (40.3% vs 39.6%). LLM conversational tools can clarify facts, yet trust still relies on doctors to make an impact. #MedSky #MedAI 🛟

🧪 Huge news! We've always thought the brain was a single organ. This study says it is two! We assumed the brain grows from a single type of starter cell. Instead, two separate cell lineages develop side by side: one builds the front and middle of the brain, the other builds the back. #Medsky 🧠

Medical training faces a new calibration gap as AI enters the clinic. A trial of 111 medical students showed that fluent, misleading LLM explanations degraded diagnostic accuracy from 21.9% to 9.2%. "Shadow AI" can act as a substitute for reasoning rather than a scaffold. #MedSky
