- PhantomGremlin 6y agoThat's a great article. HN loves to talk about "technical debt", but software problems pale in comparison to supporting power distribution decisions made 141 years ago. Harder to "refactor" copper cables than it is to rearrange lines of code. Still, they seem to have done a good job updating things while maintaining "backward compatibility".
