Google will finally launch Fuchsia OS soon, albeit on just one smart home device
Fuchsia OS has given rise to confusion and often vastly conflicting reports as to why Google has been developing it over the last few years. For example, it has been thought that the platform is intended to run on the OEM's full gamut of devices for a 100% unified, first-party ecosystem experience, an idea also behind the implementation of HarmonyOS at Huawei and almost patently inspired by Apple's current hardware/software model.
This might mean that all kinds of devices worldwide, from Chromebooks to wearables (and perhaps even the kinds of phones that currently run Android), would switch to Fuchsia for seamless integrations and interactions between a given user's personal electronics in the future.
Then again, when Google's Hiroshi Lockheimer finally admitted Fuchsia OS was a thing back in 2019, he intimated that it might be reserved for IoT and smart home systems instead. Now, it seems this goal has come to fruition, as the Nest Hub is now slated to become the first device to switch to the new software in 2021.
The resulting UI change is expected to be minimal compared to the existing Cast OS interface, however. Therefore, users who sign up for the Hub's Preview Program may not notice much change as a result of the major update (besides certain pages in Settings, perhaps). Fuchsia OS' first ever public roll-out is now slated to begin "in the next few months".
