The pieces are largely the same, but in a lot of ways, the tooling has _enabled_ more complexity than is necessary. Things have become specialized in incongruent ways that makes things harder. Simplicity is a constant struggle and a quality all of its own. Sometimes you have it by accident, where it then occupies the unknown known quadrant.
