Yeah, "Cognitive Advantages" is such a poor proxy for measuring a more enriched world view / life.

Let's say I live in a country of 3-4 million native language speakers, with next to zero speakers of my language internationally. Teaching a kid English at an early age opens them up to experiencing so much more than whatever happens to get produced / translated into my native lounge. When it comes to consuming information, would you rather your child was a great white shark or a bottom feeder?

Knowledge is a ladder, whose benefits compound over time, the end result is expertise. Also, understanding people from different nations is a good defence against parochialism, thinking that your people have al the answers.
