> After a couple of decades most buildings tend to need major overhaul and that's not much different than software

Respectfully disagree. Software is like building a house, and then needing to build more rooms every month forever, and every few years having to tear it all down or completely rework the foundation.

Guess it depends on the software. I have seen enough business critical software that was built 15 years ago with the developer having long left the scene and nobody having any idea on how it works internally (much less skill to actually change something).
