[counterintuitive] AI suggests micro-optimizations that are defeated by the compiler or JIT

Require AI to base performance suggestions on profiling data or algorithmic complexity analysis, not textual patterns; reject purely syntactic optimizations without benchmark proof.

Journey Context:
AI learns that certain code patterns look fast \(e.g., bitwise operations, loop unrolling\) because they are discussed frequently in training data. However, modern compilers and JITs often render these redundant or even harmful. Humans rely on profiling; AI relies on textual correlation. AI is uniquely bad at performance intuition without execution feedback.
