Like every "we are doomed" answer there's a core of truth in here: If something is used and/or changed it will probably break down. Given that and trying to use it as starting point for something more helpful: Sofware is nothing special here. Your things will - depending on their quality - break down with time, especially when you tinker with them and/or use them. You can push this further into the future using maintenance, repairing damaged parts and so on, but at some point you will have repaired so much that you will in essence have a new thing, not the old thing anymore. The task is to balance your efforts with your use case. An engine which has to work for one formula one race is constructed very different from one which has to work 200 or 300k kilometers. Again, software is nothing special here. If your software has to work for one run "doing it right" may be a luxury. If you need your software for years to come your luxury becomes necessity.
