imho Google translator has long ago solved the need to learn the language for basic communication. But language is a lot more than understanding menu at an eatery. Language is the medium that carries the culture and nationality, without understanding the language, your understanding of the culture will be very superficial. A translator app, no matter how good, will not suffice to live in a foreign country. Visiting for work or tourism, that's no problem, there is no need to speak the language for that, but if you move somewhere, you need to learn the local language.
