I would disagree about it not being "easy". Learning a language certainly takes time and effort, but the fact that even the dumbest people in society can speak fluently, that literal toddlers learn languages, shows that it's far from difficult.

It just requires turning your rational mind off, immersing yourself in the language and trusting things will work out, something which more rational/analytic people tend to struggle with. It's telling that children from non-English countries naturally become completely fluent in English by just playing video games and watching YouTube videos, while adults will struggle for years to reach conversational fluency in their second language.
