The problem goes deeper: verification is harder than generation. When writing an answer yourself, you build the logic chain from scratch. When verifying AI, you have to deconstruct its logic, cross-reference facts, spot hidden hallucinations, and only then approve. For complex cases (which are exactly what the humans were left with), the time for quality verification approaches the time to write from scratch. If the time becomes roughly equal, the AI stops being an accelerator and becomes just a source of noise that yields no productivity gains
