This ideology can only go so far. Human brains work well when manipulating objects as they are being interpreted. A graphical UI is an extension of reality. We manipulate the UI until it reaches a desired goal. This is somewhat instinctive, while remembering commands is not as they must be learned before going further. UIs are not the same in this way. A UI can be manipulated before having any knowledge of what it does, eventually giving an impression of its use. Playlists, or media controls are easy. But what if you wanted to navigate a spreadsheet? Do I instinctively know that I have to type spreadsheet move to D:3? Not likely. Clicking, dragging or scrolling on the other hand is much more intuitive to how humans interact with reality. This is true with early learning as well. Children are encouraged to learn shapes, colours and dimensions first as it is much easier than demanding them to know exactly what shapes, colours and dimensions are useful for in everyday life.
