Earlier quoted context omitted.
Honestly, most companies and projects fail completely. In my 25ish year career I can only think of a handful of lines of code that I've written that are still in production (or that I think might still be in production) and only a few employers that still exist. When you pan out far enough it all seems a bit silly.
Why is that an appropriate measure? Are chefs sad that none of the meals they created are still around?
Does a lawyer not take pride in a well-written contract that shielded their company when the client turned adversarial?
Does a former mayor not visit the parks they opened, the civil works projects that they helped organize or brokered deals for?
Does a salesman not remember their biggest sale? Their wildest outing? Their most critical conversation where they saved (or lost) a deal?
Does a restaurant manager not eventually sit down in a quiet corner of the restaurant, eat a meal in peace, and enjoy the background murmur of their patrons?
Does an electrical engineer not smile when they drive by a substation they helped design?
Does a teacher not remember their most successful students? Does a parent not remember their children?
Why would a software developer not want to know how long their projects lasted? Why would they not measure their impact in terms of messages sent, or mean-time-between-failure, or ROI / cost-to-benefit ratio, or smiles-per-hour? I'm not saying every line of code I write was one I was proud of, but I have dug into thorny problems, crafted solutions that were good enough, and been happy to see the code stay in service with only a very light touch needed to keep it on track. Of that, I am proud.
