I use AI as a rubber duck to research my options, sanity-check my code before a PR, and give me a heads up on potential pain points going forward.

But I still write my own code. If I'm going to be responsible for it, I'm going to be the one who writes it.

It's my belief that velocity up front always comes at a cost down the line. That's been true for abstractions, for frameworks, for all kinds of time-saving tools. Sometimes that cost is felt quickly, as we've seen with vibe coding.

So I'm more interested in using AI in the research phase and to increase the breadth of what I can work on than to save time.

Over the course of a project, all approaches, even total hand-coding with no LLMs whatever, likely regress to the mean when it comes to hours worked. So I'd rather go with an approach that keeps me fully in control.
