Google's New OS is Fuchsia

Google has a couple of Operating Systems on the go right now; Android and Chrome. Both of them are open source and both of them serve a specific purpose and do it well. There is a lot of evidence that they are now working on a new OS - Fuchsia, and it's not clear as to what is will be used for. It could be the OS that bridges Chrome and Android, but I doubt they'd go with something like this. The core code is lightweight and fast, so it could be an IoT solution. We'll keep you posted.

This is just speculation for now, and the only real description we have of Fuchsia is what it says at the top of the GitHub page: "Pink + Purple == Fuchsia (a new Operating System)." The question of why the project would be revealed in this way is also confusing, although when pressed on the subject during an IRC chat, Swetland reportedly said: "The decision was made to build it open source, so might as well start there from the beginning."
