Task Time Horizon Discrepancies May Explain AI-Human Performance Gap

herbiebradley · x · 2026-07-04

@herbiebradley speculates that task heterogeneity plays a dominant role when comparing AI and human performance: long-horizon tasks might resemble software engineering (SWE), whereas short-horizon tasks are difficult for AI but quick for humans. Citing previous METR research, he notes that time horizons across different domains span multiple orders of magnitude (OOM).
