> It's so strange to hear you and GP talking as if no one has ever learned a foreign language without moving to another country.

I speak three languages fluently (two prior to moving to said country; English, for example, is not my native tongue), so that's a weird assumption to make. With that said, I still think it's the most efficient way to learn a language, especially given how almost everyone's a nomad (especially in tech) these days.

I think the point is people are well aware that living in a country that speaks the language is a great way to learn a language.

The point was what's the best way to learn a language other than by having an entire country surrounding you dedicated to that language? Many / most people can't pick up their life for a year to learn a language. People have work, people have families, people have local commitments.
