I wouldn't sit here and claim Plan 9 was perfect, because if it was, we'd be using it. In particular, the issue is that you're reading raw stream of content on the way in and out of those file descriptors. This is akin to how shell piping in Unix is also just... text and bytes. This is limiting and produces many ad-hoc protocols. But take what Plan 9 was trying to do, and add to it what Microsoft's PowerShell tried to do, where you stream objects, structured information, instead of just bytes, on the way in and out of commands and files... And suddenly... we got ourselves an Erlang.

>> I wouldn't sit here and claim Plan 9 was perfect, because if it was, we'd be using it. Many perfect and awesome systems have been built that never saw significant adoption. I agree with ESR's observation: "Plan 9 failed simply because it fell short of being a compelling enough improvement on Unix to displace its ancestor. Compared to Plan 9, Unix creaks and clanks and has obvious rust spots, but it gets the job done well enough to hold its position. There is a lesson here for ambitious system architects: the most dangerous enemy of a better solution is an existing codebase that is just good enough."
