Plan 9 wasn't a failure and it wasn't the future, directly.
It was a research OS that was never even close to being positioned to market, be it consumers, servers, etc -- although technology coming out of Plan 9 did make it into some commercial applications.
Indirectly, Plan 9 technologies (or inspired successors) made their way into real products. Linux's procfs is one notable example.
