It looks like all the replies so far disagree, so I want to let you know you are not alone. I consider a lot of different languages a form of fragmentation.

To extend a naive view, I think it would be ideal if everyone can choose the languages they want to learn and use. This would make it a bit more like programming languages. There is concentration at the top if you want efficiency of communication, but also a lot of choices to explore. Of course this wouldn't work so well with human languages, since you need something to communicate with people around you. There is a little bit more choice if you decide to learn a second language or more.

By the way, some of this is already happening with globalization. I'd expect one's first language to be whatever used where they are raised. Their second language, if they choose to pick it up, is likely to be one of the popular ones. And the third on so on would be whatever interests them.

On a tangent, there is a Freakonomics podcast "Is Learning a Foreign Language Really Worth It?" that covers some of this. The distinctive conclusion I remember from it is, it's only worth it if the foreign language is English. I guess now or soon it could be Chinese, who knows.
