A machine named Aletta is officially drawing human blood inside European hospitals—and not a single human hand touches you. ​Using AI-driven ultrasound vision, the robotic arm maps your vein beneath the skin in milliseconds. It aligns the needle, pierces the vein on the first attempt, draws the blood, retracts, and applies the bandage. ​Flawless execution. Zero human presence. ​The chilling part? 98% of patients said they’d do it again. ​No missed veins. No repeated sticking. No human error. ​In the U.S. alone, roughly 130,000 phlebotomists make their living doing this exact job. We spent years believing medicine was the one sanctuary AI could never touch—that empathy and steady human hands were irreplaceable. ​The line between human care and algorithmic precision is gone.

Medicine discovers the bitter lesson: frontier LLMs (here GPT 5.2, Opus 4.6, Gemini 3.1) outperform specialized "clinical AI" (e.g. OpenEvidence) in a blind test. Even funnier that hospital IT are more likely to approve the *specialized* versions despite them being worse.
For medical information, general AI frontier models (Google, OpenAI, Anthropic) outperformed specialized @openevidence and @UpToDate as assessed by 12 US clinicians, randomized and blinded to which model and extensive testing/benchmarks. This was not anticipated. @NatureMedicine nature.com/articles/s41591-0…

Not knowing what to do is as stressful as having too much to do. 515 studies, 787k people: Role ambiguity and role conflict are at least as detrimental to well-being and performance as role overload. Setting clear, consistent expectations is a foundation of good leadership.

An apology is not an admission that you're a bad person. It's a step toward becoming a better person—and an expression of care for the other person. The most important part is not saying sorry. It's taking responsibility for what you did wrong and taking action to make it right. link.chtbl.com/RTAdam
