This matches my experience exactly. I built a tool that sends code to three different AI models for review because the model that wrote the code can't critique it honestly. It has all the context and actively suppresses objections. The second model, with zero context, immediately finds things the first one rationalized away. Taste isn't just knowing what good looks like, it's being willing to say "this isn't it" to your own work. AI can't do that to itself yet.
