Key statement "Specific type of failure". In theory any particular piece of large software has tens of thousands of fail safes in it all ready. For example, when you send an oversized buffer to an application with input checking it does not explode in a ball of flame (unlike programs from the '90s) and warns you about the problem. But that is where the analogies break down between mechanical items and software, software is far more connected internally than almost all other machines are.
