The Evolution of Communication

You've called this phenomenon of cyborgs also as that we're extending our mental self and not just the physical self. Is that something that is different now in the information age, or is that also something that's been going on? The minute we took our communication, and then we put it onto a cave wall where we took a stick and drew it in the sand, or we sent it to somebody else. And I was just thinking about the network of scientists sharing letters. Also, you've got shared knowledge then, by sending a letter to someone else,. Then you've made a backup of your knowledge, so you've increased redundancy.
