Harness Engineering Is the New Software Engineering

Short summary

As AI agents increasingly write code autonomously, the valuable engineering work shifts from writing code to maintaining the systems that enable them: evals, sandboxes, feedback loops, and observability. Historical parallels show this pattern: weavers became loom mechanics when looms automated. Software engineers should invest in learning agent tooling and model reliability—the new leverage zone.

• •Engineering value is shifting from writing code to maintaining AI agent systems
• •Historical parallels show this pattern repeats: when tasks automate, maintaining the automation becomes the leverage point
• •Career path: learn evals, agent tooling, and model reliability to stay at the frontier
