My understanding is that beyond the examples you talk about that go is being used extensively in google as a backend glue language for automation and services.
>as a backend glue language for automation and services.
Which again is not "at scale" (except in the sense that this automation manages thousands of servers etc).
It's what people used to use Tcl, Perl, Python, etc for.
These apps were the ones causing glacial compile times in c++?
Google doesn't use Go at such large scale though. Some projects here and there, and most of them small for all I've read. The most publicly celebrated ones being a MySQL front-end for YouTube and a caching-layer (?) for Google Downloads. Not exactly earth shattering applications.
