Reply #120: I am talking from a purely science point of view.

And I know Spanish. You can whine about culture or philosophy or anything else you want.

The science if Etymology states, clearly, that language evolves and changes, and that as cultures co-mingle, they cross-contaminate each other language.

Bicker all you want, call me names if you like. Science is on my side, period.
This planet will, in 300-500 years, speak a single language.

Like it or not, English or not, it will simply happen.

Now, I am not saying that scholars won't exist, scholars that can speak, quite fluently, the current languages. Now that we're in a written age and a recording age, languages cannot ever die. All currently known languages will still exist in the future, and there will be some, select scholars that study them and can speak them.

Again, that does not change the fact that all people will still speak one common language.
