Yeah, my mental model at this point is there’s two components to building a system: writing the code and understanding the system. When you’re the one writing the code, you get the understanding at the same time. When you’re not, you still need to put in that work to deeply grok the system. You can do it ahead of time while writing the prompts, you can do it while reviewing the code, you can do it while writing the test suite, or you can do it when the system is on fire during an outage, but the work to understand the system can’t be outsourced to the LLM.
