You seem to be cherrypicking the heirloom quality physical items and comparing them to programs that were constructed with not nearly as much care. I've owned physical objects that were worthless a few months (cheap throwaway), and have also worked on code that was over 5 decades old and still compiled just fine. If you construct the software with care it is entirely feasible to have something that you can run several decades from now, but that does mean that you shouldn't use dependencies which might disappear in that time. Curl or sqlite are probably fine, a dependency with a single maintainer is probably not fine. Network dependencies on DNS or NTP are probably fine, depending on the API of some 1-year old startup is almost certainly not fine.
