@yosh At my most recent workplace I spent pushing a decade and a half building out infrastructure that took us from three janky servers and a repurposed storefront on High to a global platform that was consistently cooking up about half a billion dollars in ARR. It was a hell of a story, one I'll recount some day. In the course of doing this, obviously a *lot* of information was generated as things evolved, changed, and grew.
Towards the last three or four years there I found that the most impactful thing I could do as a hypersenior engineer was... make sure smart people had good information. I could crank out solutions to problems all day every day, and I did.
But when it came time to really leave a mark what mattered was making what people needed to know—especially when they didn't know they needed to know it—accessible and correct.
Long story short, the best engineering I ever did over a very long career was... being a mediocre librarian.
