This makes me think… when you are fluent in multiple languages, what happens at cognitive level? You have the capacity to differently percept, interpret and convey the external stimuli and information. You have more choices at your disposal, more colors to paint quite beautifully your thoughts about external world. Yes, we all understand that given the AI trend, we are all able to translate everything in a sec., but this will not boost your brain cognitive capacity, therefore will not have any positive impact upon your behavior. So, in case you were thinking to start to learn new languages, maybe this could help you to go for it, and much more, just encourage your children, students and friends to learn more languages, at least to be willing to understand basics of more than one language, as this will put them in contact with more than one culture, will be able to have an open mind and to be less biased later in life. Now the question is: what language are you looking for to merge with?
