What stood out to me is how much of this worked because of strong abstraction boundaries. It’s interesting because we don’t often think about OS-level abstractions in the same way anymore — but projects like this really show how powerful they are when they’re done right. Makes me wonder how feasible something like this would be with modern systems, where things feel more tightly coupled and security constraints are much stricter.
