I attended this same talk last month at NDC London. Very interesting talk with lots of little details, and a brilliant speaker.

The "angular" npm-package is for angular1 only though, angular from 2+ forward is located in the @angular namespace on npm. So a more correct package to compare to would be something like @angular/core, or if you want to track all versions combine angular and @angular/core.

edit: looks like angular had 1 million downloads last month and @angular/core 1.7M.
