From TFA: "When I see these modern interfaces and all these animations/transitions, I get sudden emotions which seems good, but that fades away quickly and after that it turns out all too noisy. There is no serenity in it." He's getting sudden emotions? What does this even mean? And do I really need "serenity" in a GUI? For me, the real problem with GUIs is that it's not easy to repeat or automate a task.
