We have 195 countries in the world and civilized countries now facing a real challenge that how they can exchange their goods and services as well as interact with other people of the world. Some standardized languages available for this task so as some currencies, but the real challenge is if one country accepts one language what will happen to other languages as well as when one country takes one currency then other currencies may felt undersized. The question is world wide acceptance. English language got this field in first place but other languages also fighting for the position, while US dollar gets in first place but other currencies have tendency to overcome the situation, I believe it is finest time to build world currency and a language. So that human endeavor could find the easiest way to express and exchange.
