What’s a MacBook, what’s a pc, the thought of hardware defined systems was archaic in the early 90s how are you people still entrenched in this bullshit. The system exists as a disparate set of interfaces guaranteed to have hardware backing them up somewhere over a good network and that’s all the system needs to know. Agnostic of hardware and software version minutae and even general OS constraints the 9P passes through all equally regardless of actual hardware location. In the distant past the promises of utility were kept by having locked down systems of stable pieces, the plan9 lets these promises be fulfilled by having the necessities be allowed to be freely and transparently mounted from anywhere in the system even across different architectures and component versions.
Computer is over, the system has begun.
