Our language is, for sure, an intrinsic part of what we are. Indeed, it's the only part!
Laas will, no doubt, disagree. So, I wish he could tell us what more could be intrinsic to our identity. Genes, for example? Nonsense! An Estonian somewhere in your family tree isn't enough. You also have to be able to say "Ja, ei, kao pikalt..."
How many languages will remain on earth by the year 3000? That's a long way off, so no one can guess. Even if they could, who cares?
Let's savour our language here, today. Let's encourage our young people to learn it. There's intrinsic worth in that!

Some experts feel that the complexity of Estonian grammar and spelling makes it suitable for cyber defense, to be used as a variant of the 'Enigma' code in some ways. [The Enigma was a type of enciphering technique used by the German armed forces to send messages securely in the previous world war]. More common languages tend to be “simple”, in the sense that a noun is usually spelled the same way whether it is used as subject or object in a sentence. Estonian nouns, by contrast, are spelled differently depending on how they are used in a sentence. So, development of the cyber security aspects of Estonian make it ideal that way. And, in this way, Estonian language will have a very long life.

It is only spoken by Native Americans.
It features complex syntax and dialects.
It is unintelligible to anyone without extensive exposure to it.
At the time of WWII, there was no written version. ...”
