A major problem we have is that computer programming is not engineering as people like to say. An engineering discipline VALUES redundancy and is always designing for safety. Programming likes to think of itself as math, and deliberately choses less redundancy for the sake of convenience and speed. The classical example is how operating systems are written with languages that allow an index to be out of bounds. We now have systems that are glued together using bubble gum pretending to be safe, when they fail in the most horrible way when one of the links break.
