+
+Citadel Securities' strongest counter-mechanism to the AI displacement doom loop: all prior general-purpose technologies — steam engines, electricity, internet — followed S-curve adoption patterns with slow initial uptake, rapid acceleration, then plateau as marginal returns diminish. The physical constraint is compute: expanding AI automation to cover the next 10% of tasks requires exponentially more compute than the previous 10%, because the remaining tasks are harder to automate. At some point, the cost of additional compute exceeds the labor savings, creating a natural ceiling.
+
+This directly challenges the "self-funding feedback loop" framing where AI displacement accelerates without bound. If S-curve dynamics hold, the displacement crisis is real but bounded — there's a natural inflection point where adoption decelerates even without policy intervention.
+
+The counter-argument: prior S-curves involved physical infrastructure (steam pipes, power lines, fiber optic cables) whose deployment was constrained by physical geography and construction speed. Software deployment has no such constraint — once an AI agent works for one company, it works for all companies simultaneously. The S-curve argument may be an analogy to an era with fundamentally different deployment physics.
+
+Feb 2026 labor data supports the S-curve position in the short term: software engineering demand was still rising 11% YoY, and the St. Louis Fed Real-Time Population Survey showed AI workplace adoption "unexpectedly stable" with "little evidence of imminent displacement risk." But this data is consistent with both hypotheses — either S-curve plateau or pre-acceleration lag.

+- [[AI labor displacement operates as a self-funding feedback loop because companies substitute AI for labor as OpEx not CapEx meaning falling aggregate demand does not slow AI adoption]] — the claim this directly challenges
+- [[the gap between theoretical AI capability and observed deployment is massive across all occupations because adoption lag not capability limits determines real-world impact]] — Anthropic data supporting the S-curve lag interpretation
+- [[knowledge embodiment lag means technology is available decades before organizations learn to use it optimally creating a productivity paradox]] — organizational absorption as S-curve mechanism
