That article is very flawed and also misses a critical point about UI in general, the reason why Windows feels like Windows in the last 20 years is because of UI/UX, I used Windows all my life and when I have to open a new app eventough I never used it before I can naviguate easily, everything makes sense, I click it does what it's supposed to, pop messages are all the same, menu looks the same, they all follow the same standard. It's like driving a car, you can have thousand of different models and yet you get inside one you can drive it right away. You don't have that kind of usability if everyone was doing custom GUI running with a game engine. Same reason why there is a learning curve with UI in games, every games are different so every UI are also different, it takes time to naviguate properly in a new game. Consistance is key.
