Why Agent Hype can fall short of reality
summary
METR measures time horizons by mapping human task completion minutes to model 50% success points (Claude 3 Opus ≈ 4 min, o1‑preview ≈ 15 min) and finds a steady exponential trend, yet a randomized controlled trial with 16 expert developers on large OSS repos using Cursor Pro with 3.6/3.7 shows developers are 19% slower when AI is allowed. Explanations include low AI reliability, high repository context and task interdependence, suboptimal capability elicitation, and benchmark saturation.
