When you build software with an AI agent day to day, the thing you run out of first isn't intelligence — it's context. The window is finite, attention inside it isn't free, and a session that starts sharp gets duller as it fills with the exhaust of the work: verbose command output, whole files read to find one function, stale documentation, the residue of three tasks ago.

Here is a shift that has already happened, whether or not your documentation noticed: a large and growing share of the readers of everything you write are no longer human. They're language models — reading your docs to answer a question, your README to use your library, your marketing page to tell someone what you do. Andrej Karpathy has been making this point for a while, and it lands harder every month: the primary reader of a lot of your writing is now an LLM, and you are probably still writing for a human.
