Interesting article in that it brings bits of information about Fuchsia from a business/investor perspective rather than a technological perspective.
Some oversights though. There is no mention of the Pixelbook which is the first mass-marketed Google designed chromebook. The two previous Pixel chromebooks were limited edition high end (and high prices) devices. Also, the Pixelbook can run Fuchsia today albeit through a convoluted installation path.
Fuchsia is presented as a project to design a legacy-free kernel/operating system while incorporating the insights gained from the birth and evolution of Android and ChromeOS.
This goal is similar to that which was originally pursued with BeOS and it is good that some of its developers are ex-Be employees.
Much is said about the risks associated with breaking away from the current Android and ChromeOS ecosystems. However, Google has already demonstrated the viability of an intermediary layer to run Android applications within ChromeOS. And, in a very simplistic view, ChromeOS is the Chrome browser code compiled with a customized Linux kernel into a single image. Since the Chrome browser code is concurrently developed for multiple operating systems, adding one more (Fuchsia) should not be that difficult.
I believe that the intent is more than a senior-engineer retention project as the last sentence of the article would allude to. Will have to wait and see how the story develops.
