Do you think English will ever stop being the world's lingua franca?
Lingua franca, according to Wikipedia, is a language or dialect systematically used to make communication possible between groups of people who do not share a native language or dialect, particularly when it is a third language that is distinct from both of the speakers' native languages.
I've read that French used to be world's lingua franca. Then it was replaced by English and now we can find English speakers all over the world. Do you think this situation will change in the future? If so, what language do you think will be the new world's lingua franca? Chinese, French again, Spanish, German...?
