The cost of porting software between languages just collapsed from "hire a specialist for 4-8 weeks" to "give an AI the repo and check back tomorrow." This guy pointed Codex at the original SimCity C codebase, didn't read any of the output code, did very little steering, and had a working browser game in a couple of days. To understand how wild that is, you need the history. The SimCity source code went GPL in 2008 under the name Micropolis. Since then, three separate developers have attempted full ports to modern languages. Don Hopkins spent years recasting the C code into C++ classes for MicropolisCore. That required deep understanding of 1989-era memory management, tile engines, and simulation loops written to fit inside 640K. Jason Long spent months rewriting it in Java. Bil Simser started a Unity C# version and blogged an entire series documenting the pain. Each port required someone who understood both the source and target language, could trace simulation logic through zone evaluation and tax collection, and held the full architecture in their head while translating piece by piece. The AI did the same class of work in a weekend. Memory model translation, event loop restructuring, graphics pipeline conversion from C pixel manipulation to browser canvas rendering. All handled by the model, with a human who never read the code. Every company sitting on legacy COBOL, Fortran, or old C++ codebases is staring at a migration cost that just dropped by 95%. And that number is only going down.

Every enterprise AI project, in order: 1. "Our data is pretty clean" 2. Three weeks inside a folder called FINAL_v2_USE_THIS 3. "Okay, it's not that clean"
