Written vs Oral tradition When one of the two is better?

  1. Writing has certainly destroyed lot of important Trees.
  2. It takes lot of efforts to write, while speaking is a better option.

With advent of modern computing abilities it looks very apparent… the next step in Human evolution can be “Sound” based communication, recording and retrieval. People have started talking to the computer to get their activities done.

Again… it is nothing better than thinking and getting things done instantly. Why put efforts even to talk?
