The actual project itself (a pxe server written in go that works on macOS) - https://github.com/pxehost/pxehost - ChatGPT put the working v1 of this in 1 message.
There was much tweaking, testing, refactoring (often manually) before releasing it.
Where AI helps is the fact that it’s possible to try 10-20 different such prototypes per day.
The end result is 1) Much more handwritten code gets produced because when I get a working prototype I usually want to go over every detail personally; 2) I can write code across much more diverse technologies; 3) The code is better, because each of its components are the best of many attempts, since attempts are so cheap.
I can give more if you like, but hope that is what you are looking for.
I appreciate the effort and that's a nice looking project. That's similar to the gains I've gotten as well with Greenfield projects (I use codex too!). However not as grandiose as these the Canadian girlfriend post category.
