I'm quoted in today's @sfchronicle.com on the important @science.org study published today by @adamrodmanmd.bsky.social and colleagues. tl;dr - diagnostic AI is strikingly accurate, but (contra the Silicon Valley mentality) it isn't going to replace doctors anytime soon, or probably ever
sfchronicle.com
AI outperformed doctors on diagnosing tough cases — but is it ready for real patients?
An AI program put to the most rigorous tests in modern medicine aced its exams, and in fact performed better than human doctors on reasoning tasks such as making emergency room decisions.

If any pro-vaccine study did something like this, the anti-vax movement would broadcast it so loud and make it the centerpiece of a documentary. But, bc the anti-vax movement is fundamentally about eugenics and propaganda, they'll just hand-wave it away, play the victim, and move on.

In this context “institutionalized” often means hospitalized, because disabled people who can’t care for themselves in the community inevitably get sick. They then remain hospitalized even after recovering because there is no safe place for them to go. Bad for everyone.
