Vibe coding stats from production:
20% → Thrown away (exploratory features that didn't make the cut)
40% → Deleted after simplification (refactored or deprecated)
40% → Still running in prod
So only 2 out of 5 lines survive long-term. This matches the reality that most code written during rapid iteration is disposable scaffolding. The real value is in the learning loop and the 40% that actually ships and stays.
