# Mineral Intelligence

> A working definition written for this wiki from the reading notes; not Antikythera's own wording. From Antikythera Wiki (https://antikythera.wiki/terms/mineral-intelligence), an independent guide to Antikythera's published work.

Bratton's name for AI at geological scale: after epochs of animal and plant cognition, the planet's rock now thinks, because humans ("the fire apes") learned to etch metal and silicon into fine shapes and pass current through them. The phrase appears in the Antikythera research article and the Cognitive Infrastructures film; the SPoC lecture has the same passage as "make rocks think". Its work is to naturalise computation: intelligence is something Earth does with its own material, first folding matter into prefrontal cortices, now into chips, so biosphere and lithosphere become joint substrates of sapience in a relation Bratton insists is not zero-sum. It underwrites Planetary Computation as a planetary organ, Vernadsky's Noösphere read as geology, and Bratton's Artificialization. It is an image rather than an argument: what thinking rock shares with thinking tissue is asserted, and Tripaldi's Substrate Agency would ask whether silicon and neuron do the same thing.
