Google To Rollout Fuchsia OS

 Google will begin to roll out its new Fuchsia OS. The rollout will begin on the first-generation Nest. 

"Fuchsia is about just pushing the state of the art in terms of operating systems and things that we learn from Fuchsia we can incorporate into other products" - Hiroshi Lockheimer, SVP at Google for Android, Chrome, Chrome OS Play, Comms and Photos

The Google Nest Hub is currently running Cast OS. Google claims that Fuchsia OS will provide an identical experience.
