Thanks for sharing that, I'll read it! I do agree that comments, documentation, and other artifacts aren't sufficient to solve this problem. The closest I've come is with formal specification, where the intent of the program can be communicated very clearly. Multiple approaches are needed. One of those approaches is continuity: Keeping people around who are familiar with the code base and can pass on this knowledge to others.
