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

1.22K 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?

Imagine you have a bike, and it’s running really well. You just need to oil it up with SuperBike™ lubricant before every ride.

Eventually, the company that makes SuperBike™ lubricant announces that they’ve developed a new formula called UltraBike™ which is better and cheaper to make. As such they’re no longer making the old lubricant.

The problem is that your bike, as is, won’t work with the new lubricant. So if you want to keep using your bike, you need to do maintenance by installing a new chain.
