@gnusocialjp Agree in some places.
In the internet, mostly fine with translation software. Technology is getting better tho. But daily life depends on their business life. If work in international or multinational company, we may need to use foreign language at least English if not English natives. I mean, we may have them as friends and closer to our daily life (outside business). If we only want to know facts, then it's enough. Like @gnu2 said, language has something more.
