Right sure, but why specifically should they? What is gained or lost one way or another, if its just a matter of one mental model vs another? Models are definitionally useful abstractions, right? They aren't better or worse necessarily by only their bearing on reality, but what they do for us as models. So again, what's at stake here? What is the correct/good model we should have (instead of the autocompleter one), and what does it give us or articulate that others can't?
