It's a tenuous analogy. DRAM, disks, caches...effectively the entire memory hierarchy is implemented as message-passing. Flip flops can be well, flipped, but those are super low-level. Almost all the rest of it requires you to send messages. It's kind of ironic that all those messages basically orchestrate the illusion of global mutable state.
