Biologist Mark Pagel shares an intriguing theory about why humans evolved our complex system of language. He suggests that language is a piece of "social technology" that allowed early human tribes to access a powerful new tool: cooperation.
Whether we like it or not, planned for it or not, It's inevitable. At some point of the future we might be all speaking one world-wide unified language. This, triggers a lot of very important questions such as: What will happen to different cultures? How will the link between human language and human behavior be affected? What about the special characteristics each language has?
Another very important thing was addressed in this presentation which has more of a security aspect: The Learning process. How human beings learn from each other by inspection, how they develop and communicate just via thoughts and language. How can some person be more dominant or "Control" the other person. Transmission of many human specific things using just language and the power of the human brain.
Even though it's not quite "an awesome" presentation (I caught a few flaws and I have some counter arguments based on scientific proof but, I'm not here to criticize), you have to check this video out.
