Man, I'm sorry. I watched your comment get downvoted as I upvoted it. It's useless. I agree it would be nearly an impossible feat to develop a secret language but that's where humanity would overcome imho and that's where the focus should've been. Deception is a powerful tool. Nuance. Duality. Body language. The English language is a bitch to learn because of all the synonyms and homophones. Secret government codes. There are lines there. Realistically the world would not bet on 3 people rather than going to town on secret languages and deception. But thank you for making me feel like I'm not a total outcast here. I really did love Three Body Problem.
