Learn by doing — concepts you uncover as you read.

Humanity's search for artificial intelligence has been in service of these two qualities.

The axes so far

Two levels are named. Anything deeper still carries a handle — TC.1.1.2, SA.2.1 — shown on the spoke and listed under the wheel as it appears, so the structure stays arguable before the vocabulary is fixed.

Names attach to position, so renaming one never disturbs the rest, and an unnamed axis keeps working underneath a named parent.

Two methods on it

VLA takes pixels and words to motor commands, learned from human demonstrations. RL takes a reward and a rollout budget and finds the behavior by trying. They are close to opposites on this wheel: VLA reads a rich, partially observed world far better than RL does, and RL supplies its own experience where VLA has to be handed every hour of it.

A reading is a claim about how much of one axis a method absorbs, and it is made at whatever depth the wheel is split to — Observability is a sharper claim than Task Complexity. Drag a handle and the axes underneath it inherit the new value; split further and you can disagree with yourself in more detail. Nothing is saved: copy readings exports the whole set, ready to paste back over METHODS in autonomy-radar-data.js.

Problems (loco-manipulation) come next, on the same wheel.
