馃幆 Claim
When tools draft, sort, and summarize for you, they mostly eat the habit plane: inherited conclusions, reactive loops, cognition that runs like muscle memory. What stays yours is the metacognition plane: noticing which parts you outsourced, and learning to think ahead of your thoughts.
馃搼 Grounding
Octopus arms carry more neurons than the central brain and run segmented local control; the central brain sets goals while the limbs handle sensorimotor detail (Zullo et al., 2025). That split maps onto two planes: the habit plane (fast, habitual inference; inherited conclusions, reactive loops, outsourced drafting) and the metacognition plane (slower, deliberate reflection; noticing which limbs you outsourced and steering among them). Dual-process accounts use the same fast/slow band split; AI assistants occupy the first band more than the second. Source: Neuronal segmentation in cephalopod arms (Nature Communications, 2025)
