I've read the article and found nothing to substantiate "without reading the code".

But then, I suspect the article is AI slop. Take this:

> Christopher Ehrlich just did something that would have taken a team of engineers months. He pointed OpenAI’s 5.3-codex at the entire SimCity (1989) C codebase and let it run.

No, that wouldn't have taken engineers months.

> Four days later: the game works in the browser.

So someome used a (very slow) program to translate a program.

> No code reading.

What?? Osmosis, then?
