Earlier quoted context omitted.
Try code large a GUI project without OO.
Facebook is written in React. React is (almost) without oo. There are web and mobile guis written in React. Native aren't, yet, but that's mostly because it's young and there are no libraries for that.

Re "The model is a data structure and the view is a series of functions on it." This is exactly how I see my OO-based GUI programs. The object I define is firstly a data structure. Then I want some operations/views on it? define methods on it.
