Andrew Ng frames AI engineering as a broader responsibility than operating a coding assistant. His skills map connects building AI applications, understanding software fundamentals, directing coding agents, and deciding what should be built. The connection is practical: an AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → can implement a specification, but someone must choose useful requirements, recognize engineering tradeoffs, and evaluate the result. Ng says the map synthesizes more than 10,000 job postings, structured interviews, surveys, and other material. It offers developers and hiring teams a framework for considering those complementary abilities.
