Hidalgo's term for the process by which know-how escapes individual minds and embeds itself in objects, institutions, and systems that persist independently of any single knower.

A hammer crystallizes metallurgy. A compiler crystallizes computation. A large language model crystallizes the connective tissue between every domain of human thought ever committed to text.

The concept provides the critical lens for distinguishing between knowledge accessed through a tool and knowledge embedded in human and institutional fabric.
