When you watch a senior engineer work with AI tools like Cursor or Copilot, it looks like magic. They can scaffold entire features in minutes, complete with tests and documentation. But watch carefully, and you’ll notice something crucial: They’re not just accepting what the AI suggests…. They’re applying years of hard-won engineering wisdom to shape and constrain the AI’s output. The AI is accelerating their implementation, but their expertise is what keeps the code maintainable.

Junior engineers often miss these crucial steps. They accept the AI’s output more readily, leading to what I call “house of cards code” – it looks complete but collapses under real-world pressure.
