Given its status as one of the great American business biographies, I decided to read Titan, on Rockefeller, a couple of months ago. (I also paired it with a little of Tarbell’s history.) Titan is an impressive work, clearly the product of prodigious research. Assorted points…
The part of the Charlie Sheen documentary where Heidi Fleiss rips into him for testifying against her is pretty great
This is indeed a great post
My modest proposal for how to acknowledge AI work is to use the Latin phase "Fieri Iussit," which means "commanded to be made," a common phrase on Roman Empire buildings. You didn't make the thing, but you commanded it be done, so the acknowledgement is "Ego hoc fieri iussi."
We made water safe with filtration & disinfection. Now we can do the same for air with ventilation, filtration, and germicidal light, as illustrated in our latest @WorksInProgMag piece. (1/10)

The Extreme Inefficiency of RL for Frontier Models 🧵 The switch from training frontier models by next-token-prediction to reinforcement learning (RL) requires 1,000s to 1,000,000s of times as much compute per bit of information the model gets to learn from. 1/11
I dug a bit into this fund after the media reports, and even as a cynic my conclusions are as follows: 1. Their public long book is very good. Obviously it is concentrated and AI themed but it is idiosyncratic, tactical, and has a lot of selection alpha. Not disguised Qs beta.

I think as more day-to-day writing becomes AI-generated, it's going to really change how people read. Particularly in a work context, if you're not sure a human writer thought through the different sentences in the document, you'll value it less

It's kind of nuts to me that the nuclear reactors at Chernobyl that didn't blow up continued to operate and provide power into the late 90s. The workers commuted from like 30 miles away because the surrounding area remained evacuated
NIH grantmaking appears to be back on track! Withholding science funding was a major unforced error. Very glad to see this reversal.

I joined Teach for America in 2010 near the peak of its prestige — ~60,000 applications, some 10% of Harvard's graduating class went into the corps it was hard work for low pay, but it also felt deeply meaningful, paid off a good chunk of my student loans, gave me a huge social…

When the Luigi thing happened I do think there was a disgusting valorization of him by too many people on the far left (obviously not all of them but a significant number), so I get why everyone including me expected that to happen here again but it didn’t actually materialize.
