I can imagine a future where what's true generally describes itself (like terraform on drugs for software :p) Imagine software that is fully self descriptive and would no longer require engineers to individually interpret what's happening because the software would tell us. The system would be a graph of every single component and all possible connections between them, and all variants of each component and state that it could be in. When we introduce a change we would be aware with perfect information about the affect to the states and the paths between them. In the example the Mental Model was at a level too shallow, it should have only affected the paths between the autofocus and the user. But the bug necessitated a larger mental model (the author was considering too small subsection of the graph). I'd hope in the future we could reach a state where the program could have detected that the frame refactor would have an affect on the autofocus and all other components instead of being an implementation detail.
