Ian Johnson defends harness engineering
Original: I keep getting the same pushback: "harness engineering isn't real engineering; you're just typing words at a model." I disagree, and I finally wrote down why.
Short summary
Ian Johnson defends harness engineering—the practice of building with AI models like Claude—as legitimate engineering work against critics who dismiss it as mere typing. He argues that working effectively with AI requires real methodology, problem-solving craft, and engineering discipline. The piece makes a philosophical case for recognizing AI-augmented development as a genuine engineering practice.
