Well, from my standpoint I think that could be good If we are talking about it under the globalization flag. But, we have in front a very big problem, the language are more than a amount of letter with meaning, they are a relfect of the cultures that speak them... so we cannot be according with that idea. Because we would be restricting the natural expression of the different cultures around the world. So, I have my soul dividided: In one hand the idea of the eficiency that entails one language is really atractive, but in the other hand, and at the same time I cannot support (totally) that idea. Because the progress always been because a blend, and perhaps the mixture into the languages evolve bringing us a new understanding of the world.
