Report #81707
[counterintuitive] Can AI reliably optimize my codebase for performance?
Reject AI performance optimizations that change algorithmic complexity unless you provide concrete data distribution profiles and benchmark harnesses for the AI to verify against.
Journey Context:
Humans are often overconfident in their intuitive Big-O analysis but generally conservative in changing working code. AI is confidently wrong about hidden constants, cache effects, and real-world data distributions. It optimizes the theoretical model, not the running system, leading to catastrophic performance regressions under distribution shift.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
