This is obvious. The problem is that not everything has an API, while everything has a human-oriented UI.

Right - we did this benchmark because we launched a plugin that makes APIs programmatically from an app's human-oriented UI (from the event handlers, to be specific). So any app that has a human-oriented UI now has an API.

The benchmark is a more generally interesting part of the launch materials, so I figured it had its own separate home here.
