> All the big SoC vendors would have to get on board and rewrite their milions of lines of their kernel code on top of Fuchsia. Apple's PPC to x86 transition was successful, as was their Carbon to Cocoa transition. If you want device driver specific examples, Microsoft's Win9x to XP transition was successful, if lengthy, as was its transition to WDDM for video drivers. SoC and other hardware vendors go where the money is; they may grumble and drag their feet but they will make the transition if it's required of them.
