Should we rescue endangered languages?

[Mister Agenda]

I recently listened to a webcast about how Alaska has made some of its native languages official state languages, in an effort to promote efforts to conserve languages that are in danger of becoming extinct.

Is there a point to spending money to save a language from becoming extinct?

I think that ultimately, the only thing we can do to 'save' them is record them for posterity well enough that someone who really wants to can still learn it. Maybe in a Rosetta Stone teaching program.
