Summary

Six months after his first wave of AI essays, Rocklin updates his thinking with one central revision: AI's surprising value isn't super-human depth but super-human breadth. AI rarely beats the best human specialist in a narrow field, but it can be a B+ engineer, lawyer, and accountant simultaneously—and most real, valuable work lives in the cracks between disciplines where humans collaborate poorly. His second major theme is building feedback systems so agents can converge on good answers autonomously: give them broad context, fast and thorough feedback, and stay human enough to notice when work feels wrong. He illustrates with examples from running Coiled (connecting agents to QuickBooks, contracts, logs, and legal docs), rebuilding Dask in Rust to expose telemetry for agents, and a Python profiler (Wiretapp) that lets agents query execution. He concludes that the job has shifted from understanding systems in detail to building systems that understand and improve themselves—while humans must get better at stepping back and thinking.

Key Insight

AI's transformative power lies in its breadth across disciplines and its ability to self-improve when given broad context and strong feedback systems, shifting the human's job from mastering systems to building systems that improve themselves.
