Usually, the people who espouse such views are never the speakers of dying tongues.

I'm not saying your view is the wrong one, or that it isn't rational. The sentence in the beginning of my post was spoken by an anthropologist who studied a tribe who was losing its language, and yet didn't completely grasp the other, mainstream language, fully. I never forgot that sentence. The youths of the tribe, he said, were in a constant limbo, their language and culture dying, and never part of the bigger, dominating culture. Their children's children will probably be ok, will probably be fully assimilated, but to not think of the fate their parents and grandparents is not right.

Many efforts are futile, but it doesn't make them all wrong. Sometimes it is the right way to act.

Additionally, there is a richness of thought and experience that other languages bring to the human experience. Just google for "untranslateable words that should exist in English" or something similar.

Not to mention that even computer languages have a similar quality: different languages allow one to think about things in different ways. How much would computer science suck if the only language available was Fortran 77?

I'm not so sure about the richness, though I get your point. (I recently pondered about the german word "jenseits" not in the sense of heaven, which it may mean, but rather as a pompous form of beyond).

I agree with the FORTRAN 77 part. But this is a misleading example. This "small" language has a very specific audience in scientists and engineers (not even computer engineers). I think the point the top comment makes assumes we all wrote something like python with C and FORTRAN extensions used when appropriate.
