Looking at all the commentary going on about google building own silicon with the launch of Pixel phones, it makes you wonder if this is where Fuchsia fits in the larger picture.
Building custom silicon is one thing but if you can build custom kernel/os to go along with it rather than patch tuning existing kernel, it can make the whole system really sing...
It's not going to be a near term thing in my opinion but it's totally possible that Google may have started the work much earlier and we are only getting to hear about this now.
Future iterations of Pixel phone's are going to be really interesting and it's possible Fuchsia may come alive on Google designed silicon....
