If it works with all of your human or even generated test cases, why do I care if it decided to use a while loop or a for loop?

Like I said above, I do know to watch out for implementations that “Work on my Machine” but don’t work at scale or involve concurrency. But I have had to check for the same issues when I delegate work to more junior developers.

This is not meant to be an insult toward you. But my not doing front end development for well over a decade, a front end developer might as well be a “human LLM” to me. I’m going to give you the business requirements and constraints and you are going to come back with a website. I am just going to check it meets the business requirements and not tell you the how. I’m definitely not going to look at the code.

I just had a web project I had to modify for a new project, I used Codex and didn’t look at a line of code. Yeah I know JavaScript. But I have no idea whether the initial developer who worked on on another project I led or whether the Codex changes were idiomatic. I know the developer and Codex met my functional requirements.
