I used to work at an online shop that among other things, sold RAM. Usually, any product sold comes with 2- or 5-year warranty if your lucky. Some RAM manufacturers were so proud of their manufacturing quality, they instead offered 50-year warranties. Now, the reasonable thing to do as a seller would have been to just limit that to something like 5 years, and then give the customer their money back if they had any issues after that. However, someone actually programmed the system to use 50 years as the warranty duration, way in the 2040s. I didn't look further into the technical issues behind that (probably not many, since the required precision wasn't seconds, just days), but that remains a great example of when not building a feature costs less than building it.
