Why does software need to be “maintained”? What about it needs to be maintained?

1.25K viewsOtherTechnology

This is totally me just being naive, I don’t work in the software realm but do have an interest possibly one day, but if we have stuff that’s been able to run (seemingly) successfully for years, or maybe even decade, what maintenance needs to even be done on old programs? Is this simply for people discovering security vulnerabilities and patching them? Is there more to it than that?

Think of it like a garden sure it might be ‘perfect’ when you set it up. But

1) Maybe you want new flowers (new features)

2) Weeds growing (bugs)

3) External factors like say a neighbor building a shed near your garden causing shade problems (new operating system upgrade changes something that you have to address)

4) Invasive species found (critical vulnerabilities)

sofware doesn’t exist on its own. Its used by others and sits atop other things. All of those factors are in constant flux and change
