Layer Collapse

Layer collapse occurs when the availability of a powerful upper cognitive layer leads practitioners to abandon or neglect the foundational lower layers upon which that upper layer was built. In Merlin Donald's framework, this is the characteristic failure mode of every major cognitive transition. The student who uses a calculator without learning arithmetic has experienced a simple form of layer collapse: the theoretic tool has replaced the mimetic foundation of numerical manipulation rather than building upon it. AI creates the risk of comprehensive layer collapse across all cognitive dimensions simultaneously. The builder who relies on AI's algorithmic processing without maintaining mimetic skills (embodied engagement with materials), mythic skills (narrative understanding), and theoretic skills (systematic reasoning) is a builder whose cognitive architecture is collapsing from a multi-layered structure to a single-layered dependency. The collapse produces efficiency in the short term—outputs arrive faster, obstacles dissolve—and fragility in the long term.
