It is my understanding that most of Google's services run on a Linux fork, which they keep rebasing and ocassionally some of their changes get mainlined. Will Google move everything to Fuchsia/Zircon? Very unlikely. I think Linux will continue to be the de-facto OS for servers. That's what people know how to use and work with. FreeBSD is cool too, but much less popular. If Linux goes away, we can use FreeBSD or Hurd. But it won't go away.
