OS is designed by Bell Labs, of Unix and C fame, but ok.

EDIT: I think some of the in-jokey, arty farty culture about it is because the rest of us didn't run with it, it's basically for hobby and personal use - so its culture now. But about any one I know who has used it enough to "grok" it kinda is like "wow if this won" because its kinda such a paradigmatically good thing whole kind of cottage industries of software may not even exist because the user would be able to write a pipe from a file that is a device to write to another one type thing.

Plan 9 is supposed to be absurd. Pull the cork out of your ass lmao
