Code Was Never the Asset: A Proof-of-Concept for AI-Era Architecture

In 2023 Karpathy said the hottest new programming language is English. Most people read that as “write better prompts.” I think the deeper reading is stranger: the English specification is the durable thing, and the code is just a rendering — generated, checked, and regenerated whenever you need it.

So I tested it. I built a tic-tac-toe game the backwards way, writing the truth layer first (the intent and the rules) and letting the code follow. Chad Fowler calls this the Phoenix Architecture, where the evaluations are the real codebase. This is my proof-of-concept for what AI-era architecture actually looks like when the spec, not the code, is the asset.
