Compute vs Cognitive Labor in AI Research
- AI research requires cognitive labor and research compute as two primary inputs.
- Whether these inputs are complements or substitutes critically impacts the potential for a software-only intelligence explosion.
Elasticity Determines AI Growth
- The elasticity of substitution between compute and cognitive labor determines if an intelligence explosion occurs.
- If they are gross substitutes (elasticity > 1), rapid growth is possible; otherwise, compute bottlenecks progress.
Estimating Elasticity from AI Firms
- Estimate elasticity of substitution by regressing the ratio of compute to labor on relative input prices.
- Use changes in firm behavior over time to empirically assess compute-labor substitutability.
