What language will our future generation speak?

Languages (and its visual variation: text) will become a secondary communication means in a not-too-remote future.
Languages were created by our ancestors as a form a communication as it's used in the animal world.
Language -- wave sound -- and written text are linear means of communication, great for logical reasoning, very inefficient for the speed of communicating human ideas.
"A picture worth thousands words", images and videos are much more efficient; modern generations (ADD kids) have adopted greatly toward this direction.
Why do people emphasize so much on face-to-face interactions and "body languages"?
How much space will it take to convert all information on the text books of K-9 into images/videos (without using a single word)? how much time the students will save in "learning" this blob of information?
Visual media (images and videos) is still limited comparing to the rate of human’s thinking activity. We have to find another carrier to eliminate the communication bottleneck.
This form does not exist today, but all signs in this computerized information age indicate that it’s coming, with a big bang. However, a series of technical and ethical barriers have to be overcomed
