Plan 9 dismantles the Babel of specialized system calls and bespoke ioctl interfaces, replacing them entirely with 9P2000: a universal protocol consisting of exactly 13 fundamental messages. By forcing every interaction—whether with a local disk, a remote network, a running process, or a mouse—to speak this identical, constrained dialect, the system achieves universal transparency. The complexity is pushed out of the verbs and into the nouns (the file paths), proving that a sufficiently rigorous grammar renders a sprawling vocabulary obsolete.
