“Zohran, they said don’t mess with him, don’t mess with the Zohran but we were ready to, but we had a wonderful time quite frankly. And he said Mr. President, we need to seize means of production and we do, we need to seize them so badly.”

The biggest consequence of LLMs seems to be the devaluation of the written word as an indicator of understanding
The bigger change is presentation, historically, these emails were visually chaotic: sudden colour changes, ALL CAPS, screenshots pasted at random. Classic signs of disordered thinking. Now they’re neat, structured, and grammatically consistent. The delusion hasn't changed, but the formatting has.

Dear [Student Name],

Thank you for reaching out. Unfortunately I cannot help you because [reason].

The em dash has been unfairly maligned for its association with the real ChatGPT tell: the "not just X — Y" thing that makes you sound like you used an English-to-LinkedIn translator

Holy shit. They're really doing it. They're doing "actually pedophilia is good now." The debasement of the American Right is complete.

In between things I've been checking in on the emails that mention "university" and uhh did we all know about this connection?

I'm guessing this might actually be useful as a negatively weighted part of a training set. Nice of them to curate a corpus of how to be a dick
Preprint w/ (rapid) analysis of Grokipedia, showing it to be “highly derivative of Wikipedia”, but differing, often on controversial topics, in that Grokipedia includes content/cites from low quality (hyper partisan & conspiracy laden) sources like Stormfront & Infowars. arxiv.org/pdf/2511.09685

Also very happy to share this very [short but also very] cool piece we worked with Eunice Shin, who joined the lab at the end of her undergraduate studies ✨✨

UCI did a little piece on the journey of my graduate student, Kath. It's a nice read!

Also includes my favorite lab group photo 🤩

*slow exhale*
The Republican president is a pedophile who has doubled my healthcare costs and let scores of violent criminals out of jail. But a Democratic mayor-elect wants to make busses free in a city I don't live in. I have never felt more politically homeless.

They're almost video-style tweets?

Here's the one on nuclear weapons, which is 40 seconds long, shot in high resolution (over 300 mb, which is atypical for a Trump video), and ends with "thank you for your attention to this matter."
