English is useful and essential to communicate the basic needs of daily life everywhere in the world. It's essential in the workplaces when talking/writing about something you know far and wide and between those who possess the same knowledge as you do for they can read between the lines.
In my mind, to communicate in another language does not only mean to switch from one language to another, this also implies to wear the shoes of another. Generously opening our mind to another culture is the whole point of the thing.
