Realizing that attitude in myself at times has given me so much more peace of mind. Just in general, not everything needs to be as fast and efficient as possible.
Not to mention the times where in the end I spend a lot of time and energy in trying to be faster only to end up with this xkcd: https://xkcd.com/1319/
As far as LLM use goes, I don't need moar velocity! so I don't try to min max my agentic workflow just to squeeze out X amount more lines code.
In fact, I don't really work with agentic workflows to begin with. I more or less still use LLMs as tools external to the process. Using them as interactive rubber duckies. Things like deciphering spaghetti code, do a sanity check on code I wrote (and being very critical of the suggestions they come up with), getting a quick jump start on stuff I haven't used again (how do I get started with X of Y again?), that sort of stuff.
Using LLMs in the IDE and other agentic use is something I have worked with. But to me it falls under what I call "lazy use" where you are further and further removed from the creation of code, the reasoning behind it, etc. I know it is a highly popular approach with many people on HN. But in my experience, it is an approach that makes skills of experienced developers atrophy and makes sure junior developers are less likely to pick them up. Making both overly reliant on tools that have been shown to be less than reliable when the output isn't properly reviewed.
I get the firm feeling that velocity crowd works in environments where they are judged by the amount of tickets closed. Basically "feature complete, test green, merged, move on!". In that context, it isn't really "important" that the tests that are green are also refactored by the thing itself, just that they are green. It is a symptom of a corporate environment where the focus is on these "productivity" metrics. From that perspective I can fully see the appeal for LLM heavy workflows as they most certainly will have an impact on metrics like "tickets closed" or "lines of code written".
