Articles like this make me feel bad. Many articles on HN do this to me, but ones like this in particular. I can sense the author's excitement, and everything sounds so profound, yet I have no clue what any of it actually means. The worst part is, even if it was ELI5, I'm fairly sure I'd still be lost. I guess I'll just go eat more Pop Tarts.

If it feels opaque, you’re in good company. One of the core ideas I work with is that part of what lets us “stay ahead” cognitively is embracing density: not because every idea must be immediately digestible, but because wrestling with dense models (math, theory, abstraction) builds the muscle. You don’t need to grasp every LASSO coefficient to feel the weight of what constraint means. And yes — Pop-Tarts are more than fine (those Hariboesque gummies recently dropped at Trader Joes is that for me.) We all need something simple now & then when the brain’s been stretched.
