My ultimate point is that source code specifies everything the software can or will do, but most of that is not part of the specification. Most of it is implementation details you don’t care about.

The entire reason we have functions and components and modules etc is to isolate engineers from the things we do not need to care about. I should not need to care about the implementation details of most software, only if it meets my retirements.

The move to AI first software development will not happen because we find a way to specify as much in English as we previously would have specified in a programming language. The move will happen when and as we figure out how to specify the things that matter. We don’t need the same rigor. We need the correct rigor.
