I don't know; I think that there's still space in the world for Plan 9 to compete. The fundamental ideas are sound, and the OS itself could be quite high-performance and secure (I won't write that it is, because AFAIK there's never been a comprehensive audit).

With virtualisation, its hardware requirements are no longer a dealbreaker.

With the rise of Go, I've been wondering if perhaps deep within Google there's a quiet use of Plan 9.
