Economists Push Back on Predictions of Double-Digit AI-Driven GDP Growth
Around Sept 10, economists Ben Moll and collaborators (Alex Olegimas, Alex Imas) published a blog post systematically dissecting the economics behind predictions that AI will soon deliver double-digit GDP growth, directly responding to claims by Dario Amodei (10-15% annual growth), Leopold Aschenbrenner (30%+), and Sholto Douglas. They conclude such predictions are unlikely on the stated timelines, offering a serious counterargument in the debate over AI's macroeconomic impact.
Confirmed
- Core thesis: growth models do not mechanically prevent explosive AI-driven growth, but the trajectory depends on a set of key assumptions the authors judge unlikely to all hold.
- Quantitative judgment: double-digit growth is highly unlikely; a reasonable baseline is 4-5%.
- The authors are optimistic about AI capabilities themselves, noting the forecast capability explosion is already underway; the disagreement is over whether it translates into explosive economic growth.
- Moll unpacked how Anthropic's economics team constructed its "15% AI-driven GDP growth by 2030" projection: a standard Solow model with particular parameter assumptions can easily produce the number, but writing down 15% growth does not mean it happens.
- The post also discusses downside risks such as cyberattacks that could drag GDP.
- In response to criticism, Moll publicly replied to jankulveit and invited him to bet, arguing that even if AGI only lifts GDP growth to 4-5%, that is hardly "business as usual" but a huge macroeconomic change.
- alexolegimas added a counterfactual perspective: sustaining even a mundane 2% growth historically required ongoing creative destruction and technological change; amid multiple headwinds, AI helping the economy stay on trend already counts as a positive impact.
Unconfirmed
- jankulveit reposted and criticized the post, arguing it overlooks key assumptions such as "AI as a customer"; this is one critic's view, and the original treatment of those assumptions needs verification from the source.
Why it matters
- The post represents a systematic rebuttal from economists to the AI industry's mainstream high-growth narrative, helping calibrate public and policy expectations.
- Moll's invitation to bet turns the dispute into verifiable forecasts.
- alexolegimas's counterfactual framing suggests that even unimpressive growth numbers would carry real value in a headwind environment.
