AI agents have reached a critical threshold in handling extended complex workflows, marking a significant turning point for how AI reshapes workplace productivity. Major research labs—METR, GDPval, and Anthropic—are converging on this assessment. The numbers tell the story: when an AI tool can cut 8 hours of work by 65% consistently, it fundamentally restructures how tasks get done. Even accounting for occasional errors or edge cases, the math changes the economics of work. This isn't incremental improvement anymore.
