Still Human Work: The Tasks That Need Judgment and Intuition When AI Writes the Code
AI can generate most of the code. It still cannot decide what to build, sense when 'correct-looking' output is quietly wrong, or own the consequences. A field guide to the tasks that stay human — for engineers and PMs.
