Android and Chrome OS are apparently not enough for Google, as the company is reportedly developing a third operating system codenamed Fuchsia. The company has been writing the new operating system for over a year, and today we get our first look at the UI of the new OS.
It's clear that Google has big goals for Fuchsia, perhaps even replacing Android one day.
Ars Technica has unveiled the Fuchsia UI. While the operating system is supposed to be for IoT devices, the UI shows that Google has much bigger plans. The new OS isn't particularly functional, but it does give us a glimpse into what Google is dreaming of.
Before we begin, it helps to watch the video below
The UI is centered around a vertical scrolling screen. In the center is a profile picture, the date, time, location, and a battery icon. Above this central space are “Stories,” which thankfully don’t appear to be any kind of Snapchat. 
Instead, it's a place for your recent apps and app groups. Below that is a search box and a selection of suggestions, much like Google Now, except it can also be used as a launcher. Tapping your profile picture will give you access to some quick settings.
Once you tap on one of your stories, you'll be taken to a full-screen app interface. If you drag and drop one window onto another in your stories list, you'll see a split-screen feature. It looks like you can combine more than two apps in one go with the simplicity of a mobile UI and the power of a desktop operating system.
There doesn't seem to be a limit to the number of apps you can have running at once, but the new operating system crashes if you overload it with too many apps. Google could of course limit the number of apps based on the size of your screen. You might only be able to work with two apps at a time on a smartphone, but four on a tablet.
What's notable about Fuchsia is that it doesn't use Linux or the GPL — unlike Android and Chrome OS. The OS's interface and apps ditch Java for Google's cross-platform Flopter SDK.
Essentially, Google is trying to use as much new, proprietary code as possible to develop the new operating system and hopefully provide a better end-user experience in the long run.
