CONCEPT
The Funnel Narrowing
Tegmark’s economic diagnosis of the AI transition: the progressive elimination of cognitive tasks that require uniquely human contribution, driven by AI capability that climbs the cognitive hierarchy itself rather than merely automating its lower floors.
For two centuries, every wave of automation displaced human labor at one cognitive level while creating demand at a higher level. The industrial revolution displaced manual laborers and created demand for machine operators; the computing revolution displaced clerks and created demand for programmers. Each transition appeared to confirm a historical law: technology destroys jobs at the bottom of the cognitive hierarchy and reveals jobs at the top.
Max Tegmark’s funnel-narrowing framework identifies the structural reason why this pattern may not hold for AI. Previous automation was narrow—it replaced specific, well-defined cognitive tasks while leaving the broader landscape of human cognition untouched. AI is not narrow in this way. It is climbing the cognitive hierarchy itself, automating non-routine as well as routine tasks, creative as well as mechanical work. The funnel of tasks that require distinctively human contribution narrows with each capability improvement. The critical question—and the question on which Tegmark declines to offer false reassurance—is whether the funnel narrows
