I've previously found LLMs to suck at "Track down cited pages/references and see if they support the citer's claim." LLMs hallucinate what the cited document says, if the citer's claim sounds LLM-plausible. I wish a CiteCheck benchmark for this kind of task would get put

I’m seeing people saying it’s sad these rich guys won’t buy cool cars. Others are saying Sam is being hypocritical because he’s been spotted driving a car that costs well over $1 million. But that’s the joke. Paul thinks $250K is too expensive, while Sam thinks it’s too cheap.

the most important thinker in AI, in my opinion, is this 23 year old. leo aschenbrenner. he has been more right, both in a testable predictive sense and in a market sense than virtually anyone else. and most importantly, he's not an AI doomer, he's not an e/acc, but rather a

It's rather strange that one of the core activities of academia—and, as far as I know, this is true across all its branches—has become the writing of texts that no one will ever read.

Most of the hate I get is understandable. Wealthy guy doing unusual things for health. Looks weird. Acts weird. Says weird things. Ok. There’s also something else going on. Ultraprocessed foods emerged in the 1970s. Those in adolescence / early adulthood (now 50-64) exposed

The human body is so resilient that, even after spending a decade neglecting it, much of the damage can often be undone in as little as 50 or 100 days.

I knew that “con” in the Spanish “conmigo” and “contigo” (“with me” and “with you”) comes from the Latin “cum” (“with”), but I didn’t know until today that the “go” comes from “cum” as well—specifically, “cum mēcum” and “cum tēcum”: literally, “with me with” and “with you with”.
