A Swiss language spoken in Switzerland 150 years from now is not a vision of a future to be, it's a mistake. An easy mistake if you're not familiar with the somewhat special ethnic situation in the country, but still a mistake.
Now, I'm sorry, but that's just wrong. In 150 years, a lot could happen..here is one hypothetical situation for you...a new political party comes in, which favours one of the ethnic groups within Switzerland.
This language becomes the OFFICIAL STAE LANGUAGE. (Doesn't mean the speakers of the other languages stop, just that this is the "lingua franca" of the state). Say it was French, for arguments sake.
This new Government is fairly nationalistic, and believes that their French is and should be distinct from French French, so they christen their dialect of French "Swiss"; and lo, Swiss is the language spoken in Switzerland.
Forget 150 years, that could happen in 5 years.
For example, Look at the situation in the Balkans. Serbian, Bosnian and Croatian were all different dialects of the same language. (Serbo-croatian, if I recall correctly). following the wars, they are now distinct languages. The way they are spoken HAS NOT CHANGED ONE BIT, but they are classed as languages because of POLITICAL, SOCIAL And CULTURAL changes.
Language / Dialect are social constructions, not linguistic ones.
It's not unfeasible for the scenario outlined above to happen: and it's certainly not worth us all getting our knickers in a twist.
