It's interesting that in the current state of software development, a programming language that have been stable for not even a year might be considered obsolete.
So inevitably, someone will ask "Is lib foo still being used? The last commit was over 8 months ago" and then people have to chime in, "yes, it's still in heavy use".
It's also kind of pointless to "update the copyright year" for individual works tied to your name, since the copyright lasts x years after your death. If anonymous/pseudonymous, then it's like 95 years after initial publication date, and you can't just extend that arbitrarily by updating the base year and nothing else every year..
