The need for people to communicate with each other has existed since we first walked upon this planet. The lowest and most common level of communication modes we share are movements and gestures independent, that is, they permit people who do not speak the same language to deal with one another. The next higher level, in terms of universality and complexity, is spoken language.Most people can speak one language, some two or more. A spoken language is a very efficient mode of communication if

But for those who can, writing is still nowhere near as efficient a means of communication as speaking. In modern times, we have the typewriter, another step upward in communication complexity. Significantly fewer people type than write. (While a practiced typist can find typing faster and more efficient than handwriting, the unskilled may not find this the case.) Spoken language, however, is still more efficient than typing, regardless of typing skill level.
