I mostly agree with the points made, however I would not call this "invisible" as it was chosen to be called in the title. Good tools should be obvious, with the main ways to use it being very low friction and low cognitive overhead. That is not the same as them being invisible. It is just a different type of visibility (one that doesn't require users to get a driving license before they can use the tool properly). When I design such tools, I tend to think about the problem from the users perspective. What is the information they really need to know? In which environment does the rest of the context reside? Which error cases exist, who will have to deal with them and what will they need to know?
