Yes, the history of knowledge pre-1400 famously has nothing to do with medicine.

How OpenAI Uses Complex and Circular Deals to Fuel Its Multibillion-Dollar Rise Here are seven unusual financial agreements helping to drive the ambitions of the poster child of the A.I. revolution.

"Many of the deals OpenAI has struck β€” with chipmakers, cloud computing companies and others β€” are strangely circular. OpenAI receives billions from tech companies before sending those billions back to the same companies to pay for computing power and other services." www.nytimes.com/interactive/...

Experimental evidence of the effects of large language models versus web search on depth of learning Abstract. The effects of using large language models (LLMs) versus traditional web search on depth of learning are explored. A theory is proposed that when

When people learn with ChatGPT instead of following their own searches, they end up knowing less, caring less, and producing worse advice, even when the facts are the same.

Friction is an essential ingredient for learning! Convenience makes us shallow.

I got to quote these lines as a guest lecturer in a modern European history course (though I’m a medievalistβ€” long story) to talk post-WWII British pop music UC Davis c. 2004. A super fun lecture to give, and the Kinks featured heavily in it. Loved their reaction to hearing about Lola.

As a later teenager (c. 1982), I was in Tower Records in Sacramento. A couple of younger kids were a couple of bins over, and one says to the other, β€œThe Beatles? That’s Paul McCartney’s old band.”

I got to see them once at the Cow Palace in SF, in 1983. Then saw Ray Davies here in Portland at the Crystal Ballroom in 2008, a really great acoustic show.

A grave of a Roman physician in Bingen dating to the 2nd c. AD contained a remarkable set of medical instruments, including cupping cups with a stand in the shape of a grapevine.
These cups were used for therapeutic suction or bloodletting, a practice with deep roots in Greco-Roman . 🧡1/ 2

Here's a photo of my friend and colleague, Jorge Bautista, getting shot in the face with a flashbang grenade. The ICE Agent is so afraid of Jorge (who was posing no threat) that he has wet himself. Please share this photo. Everyone needs to know what cowards ICE agents are.

Growing up in Sacto, I loved the neighborhoods of SF, and the bay area generally, in the 70s and early 80s. The dot com era destroyed it (for me, certainly).

Documents Allege a Federal Agent at Portland ICE Threatened to Shoot an Ambulance Driver Feds delayed medics who had come to pick up an injured protester. Then, according to confidential incident reports, the agents became aggressive.

In Portland, an ambulance was summoned to the ICE office to treat an injured protester (not clear how he was injured). But when the patient was loaded inside, ICE officers refused to let the ambulance leave and threatened to shoot the ambulance driver: www.wweek.com/news/2025/10...

What The Hell Is Going On, a thread:

I’ve seen some thinkpieces and posts about Portland protests that fail to understand the long-term hyperspecificity of Portland culture/humor, and frame it as a sort of shitposting meme-pilled ironic thing. Which is wrong.

So I’m gonna give you my breakdown.

I was at a free concert in Golden Gate Park back in the 80s, when people started throwing around the KFC buckets meant for donations, money flying flying all over and people hucking change toward the stage, and a fist fight broke out in front of me. That was fun, or rather, β€œfun.”
