I think that it's nonsense to waste disk space by sending pages in multiple languages. We need to send all the content in English. I know this is reaching a bit, but if the purpose of sending Wikipedia to a different celestial object is to protect all of the knowledge of humanity, then shouldn't all of the content be in one language? The idea of sending content in various languages is akin to an archaeologist digging up foreign tablets that have portions chiseled in different scripts. It's just needlessly complicating the task of whatever human or whatever other being ultimately decodes this information in the future.
