The Burgess Shale as AI Metaphor
The 530-million-year-old fossil deposit revealing Cambrian diversity—dozens of viable body plans, most extinct—as template for understanding AI's present: a moment of proliferating forms before selection prunes the bush.
The Burgess Shale, a fossil deposit in the Canadian Rockies, preserves the Cambrian explosion's extravagant diversity in exceptional detail. Discovered in 1909 by Charles Walcott, re-examined by Harry Whittington's team in the 1970s, and interpreted by
Gould in
Wonderful Life (1989), the Shale revealed that the Cambrian seas contained far more diverse body plans than currently exist—Opabinia with five eyes, Hallucigenia walking on spines, Anomalocaris as apex predator. Most went extinct. Their extinction was not determined by inferiority but by contingent fit to subsequent conditions. Pikaia, the modest chordate ancestor of all vertebrates, was one of the least impressive Cambrian organisms—it survived events that eliminated more complex, more specialized forms. Applied to AI, the metaphor identifies the present moment (2025–2026) as a Cambrian explosion: rapid diversification of forms (model architectures, training approaches, deployment strategies), most of which will go extinct. The survivors will not be the 'best' in any objective sense but the ones fitting specific ecological conditions produced by specific choices (regulatory, economic, cultural)
