I recently had the pleasure of reviewing some of my oldest production code from when I had first left college.

It worked, no issue there, but the amount of commentary I included definitely surprised me.

I guess I really needed the support structure of comments to keep my logic on track back then, whereas now even convoluted map-reduce one liners are things I see as just obvious literate programming.

I did go a long while in my career still writing code that way when I had to share it with people. I don’t think I stopped until the only people reading my code were senior engineers with way more qualifications than I had.

So, I wouldn’t say just from this code that the creator is an LLM.
