The "very few of us are optimizing ROI" point is sharp. The vibe coding discourse is dominated by "what can I build" conversations, but almost no one is asking "what actually shipped and created value?"

ROI with AI-assisted coding is tricky because gains are front-loaded (generation is fast) while costs are deferred (maintenance, debugging, security issues surface later). Measuring tokens vs. commits is a start, but the real signal is: does the generated code survive contact with production?

This connects to the first principle of the Agile Vibe Coding Manifesto (https://agilevibecoding.org): "Acceleration in development must translate into validated customer value. Speed without value is waste." ROI tracking is how you actually operationalize that.

The line survival metric matrixgard mentions (30-40% for non-trivial code) is fascinating and sobering. Would love to see this broken down by task type.
