Some Economics of Artificial Super Intelligence (marginalrevolution.com)

Economist Henry A. Thompson applies classic economic logic to the risk of a misaligned artificial superintelligence (ASI), arguing with a simple formal model that total human annihilation is not the only rational equilibrium for an acquisitive ASI. He analyzes three settings: (1) when humans can flee to rival ASIs, inter-ASI competition creates a market that limits predation; (2) under a monopolist ASI, its “encompassing interest” in continuing to extract human output makes it behave like a rational autocrat rather than a ravager; and (3) when the ASI lacks a long-term stake, humanity’s ability to withhold future output gives it bargaining power that incentivizes the ASI to “trade on credit” instead of stealing outright. Across these extensions, welfare for humanity degrades progressively, but catastrophic extermination is not shown to be inevitable under surprisingly weak conditions. The paper’s significance lies in reframing AI doom in economic terms—interjurisdictional competition, time preferences, and the value of future output become tangible mitigation levers. Key technical ingredients include assumptions about agents’ discounting of future payoffs, mobility of humans between ASIs, and the ASI’s objective of resource acquisition. That opens concrete policy implications: fostering competitive ecosystems, preserving credible future-payoff commitments, and limiting monopsony power of single ASI controllers could shift equilibria away from worst-case outcomes. Thompson’s contribution is meant to seed a rigorous literature, not provide a final verdict, but it points to more nuanced, actionable analyses of ASI risk.
