If you were given the job of creating a new "Rosetta Stone", which three languages would you choose, and what would you write on it?
What's wrong with Sumerian, Egyptian, and Greek?
C++, Java, and Python.
Because I know a lot of all of them.
Geek, leet, and Valley?
I guess I would go for:
English (or Dutch, German, etc)
Why? Because these three are very different from each other. From char-set to idiom and grammar.
This would increase the change that someone could translate at least one of them.
English, C and Babel (as in the fish).
