I plan to ignore the controversy on whatever's going on with Navier-Stokes. However, I also noticed my reaction was "huh, okay" rather than "wtf??????" at an AI solving a Millennium problem. (I expect the result to stand up, controversy aside.) I'm the frog, it's me, I'm boiled.

In retrospect "AI CEOs become celebrities and attract corresponding levels of desired and undesired attention" was a very obvious prediction that many people failed to account for (including me)

AI Will Not Make Your Job Chill
People keep talking about how AI will make their job easy, and I don’t really understand why.

1. Obviously terrible to have a Molotov thrown against your house, not appropriate response. 2. Of all analogies to make, "ring of power" is a choice, given the story's theme that the only way to stop the ring's destructive power is to destroy it. blog.samaltman.com/2279512

First paper since switching into AI safety team🎉 We look at problems that could be solved if the model behaved consistently over a set of prompts, and tried training that in output space and internal activations. Both were effective. See thread or paper for details.

"I don't play gacha games because they're a scam" vs "Let me do one more hyperparam sweep before giving up. One more prompt tuning run. I swear we'll beat baseline. I know it's gonna beat the baseline this time. It's gonna win. This time for sure."

The ship has sailed, but I wish the ML reporting default was % incorrect rather than % correct. It better matches loss curves and magnifies the capture of edge cases. 95% accuracy -> 97.5% accuracy = meh 5% error -> 2.5% error = omg we've halved the error rate
