Martin Casado sparks debate over lines of code as a metric for AI recursive self-improvement

a16z's Martin Casado questioned a large-lab researcher's claim that lines of code (LoC) is a reasonable metric for RSI, citing AI writing lots of AI-building code as evidence. misovalko pushes back with a bell-curve argument: models can produce nonsense in infinite ways but only a handful of right ones; past some hypothetical peak, enough invalid cases could actually make valid ones easier to pin down. What matters is whether the generated LoC carries substantive information. That peak may be task-specific, dynamic, or unreachable — but we still have to climb toward it.
