Inbox was definitely written using GWT, as were other major google products, but not gmail as far as I know.

That’s not true. Inbox was written in Angular originally. Not sure what it evolved to but it was always JavaScript.

Angular definitely did not catch on for google properties until much much later. Back when I did nothing but backbone/angular consulting, none of the major google properties used angular.
