Welcome "gulgre", if you haven't been already.

I think you'll find (and I'm sure to be corrected) that the majority of the members here would not suggest "throwing out" any language, and as you suggest, revel in the many differences, appreciate their growth, and would be saddened if technology becomes more of a "cultural" presence than language, and succeeds in eliminating even one.

If you accept that language is culture, then the English's being quite a collection of different grammars, spellings, pronunciations may be argued as already being the natural global language, unintentionally. Who would be arrogant enough and why would anyone listen to someone suggesting a vote on this subject anyway? Is someone?

Besides, there already is a global "language", it's called music... with which there is no better language to describe.

There are plenty of philosophical arguments against "Language is culture", my favourite is "A culture of one is as valuable as a culture of a billion"... throwing the chaos of subjectivity into a recipe that is trying hard to avoid this ingredient. Do I lose my culture if I decide to only communicate with musical notes from this point forward..? On the contrary, you'd lose yours in my "eyes" (as most people don't hear music as I do (that's polly a good thing).

You clearly understand language better than I do, and it does indeed (as would be expected) make sense for someone with my "culture"(assuming I have any) to argue that "Music is Culture", however, I don't believe that either....
