That's a fantastic analogy. I had a worrying discussion the other day with somebody about user interfaces. I was asserting that UIs are more than just CLIs and GUIs, more than VUIs (Voice User Interface)...UIs extend to virtually everything we do to interact with a computer. A programming language is a kind of UI, an API is a kind of UI and so on. I was asserting that when we think of the entire interaction surface of a computer, from bare metal on up, as an interface (with us as the users), then we need to make sure we design those interfaces to work well as an interaction medium because it enables "better" interaction with machines (on virtually every vector).
