Author’s note

This post is a painful read. I was going through a period of severe depression, and being asked to blog continuously without any real news. It's in here for completeness, but there is no reason to read it.

AI Notes

The June 2023 launch post for Cody, three months after Cheating Is All You Need. On the surface a product introduction — confessional war stories of being handed undocumented codebases (1990 FORTRAN, 2005 Amazon load balancer, 2016 Android), then a walk through what Cody could do in mid-2023 against the Wyvern codebase: codebase-aware Q&A, recipes, inline fixups, parallel "async Cody workers." Under it runs the thesis Steve repeats across his later Sourcegraph essays: the frontier model is a commodity, and the differentiator is the retrieval pipeline — backed by embeddings, not keyword search — that decides what the model gets to see. That argument gets its full airing later in RAG to Riches and The Self-Driving IDE Is Coming.
