So, recently went to the movie theatre to see (other than a mob of tiny snowmen with plastic forks for hands outside) the movie "Arrival". Warning, Spoilers:
The alien's language, if learned, makes it so you don't see time from a linear perspective. And, if I could choose between teaching everyone the language, and not doing so, I would choose not to. And you might be thinking "What the heck, Tiger? Why would you do that?!". Well, while it would open our minds to a whole new concept of time, it takes away a large chunk of our purpose in life. If we could see our futures, than we would be no more than mere puppets. Actors, forced to follow a script. There would be no surprises. No control (or illusion of control). While there would be some moments of happiness, would that make up for living an existence that was chosen for you, cannot be avoided, and is already spoiled for you? If a kid knows what the rest of their life will be like, why bother living through it all? It's like knowledge- if you know everything there is to know, then you would have no more knowledge to find, and your life would lose all meaning and purpose. And in teaching the world the alien's non-linear language, I would be doing something that, on a scale of ethics, is right down there with condemning everyone to eternal torture. Sure, the alien's mindset may be made for such "wisdom", human's are not aliens. Most babies would be with a vision of suicide as one of their first non-linear memory. Everything we as humans have made would fall into disarray- education, economy, gambling.
So, what do you think? What would you choose? To make humanity much more advanced, but purposeless, and meaningless; or keep humanity linear. I mean, teaching them non-linear perspective would not begranting them knowledge- it would be warping their vision and memory.
