Even if whalesong is actually a language, translation to human language could prove challenging if Wittgenstein was correct that meaning is use. Whales won't be using sounds the same way we do. Thus the "If a lion could speak, we would not understand him" quote. It's a problem we'll face if an extraterrestrial signal is ever detected. We can hope they'll use familiar mathematical patterns to help us translate like in Contact, but we can't be sure about that. They might be too different from us physiologically, culturally and technologically.
