Code is best written as text because it is logic. Sometimes we can embed data in logic or use logic to create data, and then things can get a bit messy. Sometimes it can help to visualize the logic, e.g. with flowcharts, but I don't personally believe that it is useful to do things primarily this way. The visual part of a UI is graphical data. For reasonably complex things it makes sense to edit graphical data in a graphical editor and to separate it from code. It sounds a bit in the article like he's talking about funny esoteric 2D visual programming languages but I think he just wants a nice way to make GUIs and has concluded that HTML is reasonable for doing so. I'd be interested in a graphical shell for an OS (Linux I guess) written purely in HTML and friends. You'd have completely seamless integration with the web.
