urbit’s even stupider than this, cause lisp machines were infamously network-reliant (MIT, symbolics, and LMI machines wouldn’t even boot properly without a particular set of delicately-configured early network services, though they had the core of their OS on local storage), so yarvin’s brain took that and went “what if all I/O was treated like a network connection”, a decision that causes endless problems of its own

speaking of, one day soon I should release my code that sets up a proper network environment for an MIT cadr machine (which mostly relies on a PDP-10 emulator running one of the AI lab archive images) and a complete Symbolics Virtual Lisp Machine environment (which needs a fuckton of brittle old Unix services, including a particular version of an old pre-ntp time daemon (this is so important for booting the lisp machine for some reason) and NFSv1 (with its included port mapper dependency and required utterly insecure permissions)) so there’s at least a nice way to experience some of this history that people keep stealing from firsthand
