Babies Invent Crawling, Proving Invention Is Human Core

Crawling isn't innate (unlike walking). Every baby must *invent* crawling, from scratch, using extremely little data, and no reference to imitate. Which is why different babies end up with different ways of crawling. Sometimes people tell me, "you say AI isn't...

Boredom, Not IQ, Limits Mastery—Persist to Reach Flow

The bottleneck for deep skill isn't usually intelligence, but boredom tolerance. Learning has an activation energy: below a certain skill threshold, practice is tedious, but above it, it becomes a self-sustaining flow state. The entire battle is persisting until that transition.

Clear Problem Specs Unlock Solutions, Vague Ones Stall

If a problem seems intractable, it's almost always because your specification of it is vague or incomplete. The solution doesn't appear when you "think harder". It appears when you describe the problem in a sufficiently precise and explicit fashion -- until...

GPTQ Brings Int4 Layerwise Quantization to Keras 3

GPTQ is a post-training, weights-only quantization method that compresses a model to int4 layer by layer. For each layer, it uses a second-order method to update weights while minimizing the error on a calibration dataset. It comes built-in in Keras 3...
