[counterintuitive] AI optimizes code with micro-performance tweaks that introduce memory leaks or reduce readability

Ban AI from making performance optimizations without explicit profiling data or algorithmic complexity improvements. Prioritize readability and algorithmic complexity \(Big O\) over micro-optimizations.

Journey Context:
AI frequently suggests micro-optimizations \(e.g., replacing list comprehensions with generators, caching in local variables\) because these patterns are heavily represented in optimization training data. However, AI misses macro-optimizations \(e.g., changing an O\(n^2\) algorithm to O\(n log n\)\) and often introduces subtle bugs like memory leaks \(holding references in caches\) because it doesn't understand the runtime lifecycle. Humans know premature optimization is the root of all evil; AI thinks more optimization is always better.
