Researchers Propose Autonomous Task Duration as Core AI Capability Metric

Researcher arjunrajlab proposed that the best metric for AI capability is the human-equivalent duration of tasks it can complete autonomously, claiming exponential growth consistent with METR's approach. This counters wcratcliff's skepticism that progress is more likely sub-exponential.
