I am not a big fan of the visual UI/UX either. My point is that there is more to the UI/UX than widgets and popups. With JS on hardware, we might have a new way to design HCI other than those pretty wireframes in Photoshop. IMHO, JS is a laguage designed for APIs, which is good for exploring ideas and protyping. There is always a way to push the performance to another layer, like CSS boosted by GPU.
