Blue / Green - What's the difference?

I came across an article from MIT about a study done about members of the Tsimane society in the Amazon Rainforest of Bolivia. The Tsimane who spoke only their native language didn’t have a distinction for green vs blue. However, Tsimane who were bilingual and knew Spanish, which has such a distinction, had repurposed words from their native language to make the same distinction as they would in Spanish. The bilingual Tsimane could distinguish between the two colors and therefore developed new words for them, while to the monolingual Tsimane, there was no difference.

I found this incredibly intriguing as it showed some interesting benefits from being multilingual. The Spanish-speaking Tsimane had adopted ideas from Spanish into their native language. Also interesting was the fact that something as simple as color wasn’t an innate property but rather a social construct. We don’t innately differentiate between colors, but rather we learn through language to separate them differently.

I wonder if there are more such advantages to being bilingual. Are there other aspects other than color that could be improved by learning different languages that make different distinctions between things? Every language has certain words that don’t translate 1:1 into another language. For example, Dreikäsehoch is a German word that means “three cheese high” and is used to refer to a small child who is the same height as 3 wheels of cheese. Could this distinction allow German speakers to have a better sense of height compared to English speakers?

Lastly, if there are more such advantages to bilingualism, how do we take advantage of them? Beyond the obvious one of trying to learn more languages, perhaps there is room for innovation in artificial intelligence. Could AI that is trained on multiple languages be able to more accurately understand the world?
