Yup you'd fail fast because you could not at the time bullshit and handwave the computer. When you don't do the implementation work itself your sloppiness is mostly the concern and inconvenience of implementors. And I concur the best way to understand the system is through the code, and the best way to understand the code is to write it.

We aren't going to understand the systems we whackchitect from now on. It's the endless prodding and begging instead, something that makes me infinitely sad.
