The Tension of Scaling a Model

There's always that tension because you look at it, we have this PDF that shows what this DAG looks like and it's big. I used to trace through the whole DAG two years ago and I would no longer do that. It's very much like these edges are really your assumptions. So they're all open for criticism.
