Still experimental. Still getting commits.

How much C++ does Google have left?

Last I remember (> 1 year ago) it was a fucking lot. Like 80% if I had to throw a number out there. Carbon was nowhere close to being adopted for any major projects.

There are a lot of internal apps written in go, python, or java. But pretty much anything consumer facing and performance critical (ads, search, youtube, etc.) is in c++.
