It’s not actually true that your software gets done, that’s essentially impossible unless you’re doing some kind of performance art project targeting a defunct platform from decades ago. Operating systems and libraries change underneath you all the time, even if you’re just using Linux and glibc, and if you’re not keeping up eventually your software is the legacy code keeping people stuck on an insecure OS, like those businesses who have to keep one box running DOS because of some ancient device driver for their equipment. It’s better to plan for this in advance and use a stack where upgrades are done gracefully, rather than sticking your head in the sand and pretending it doesn’t happen.
