Report #48605

[counterintuitive] AI writes highly optimized code because it knows all algorithmic complexities

Never ask AI to optimize code without providing explicit profiling data and latency constraints; reject AI optimizations that increase complexity \(e.g., adding caches, thread pools\) without empirical bottleneck evidence.

Journey Context:
AI is trained on textbooks and competitive programming where Big-O complexity is the gold standard. In real-world engineering, AI introduces catastrophic failures by adding optimizations \(like lock-free queues or custom allocators\) that destroy cache locality, increase GC pressure, or introduce priority inversion. Humans use profilers; AI uses intuition from synthetic data. AI optimizes the algorithm; humans optimize the system.
