Much the same way as it's "inevitable" that the RISC vendors will take over the world since the late '80s. Or it is "inevitable" that Intel will die Real Soon Now for the last...oh...30 years now. Or how it is "inevitable" that IBM/Mainframes are doomed for at least the last 40. How long have we been predicting that ARM will catch up...and all we have is a firm, definite 'maybe' with M2, a tech available to a single vendor?
Said another way: "You keep using that word. I do not think it means what you think it means."
