I've always been extremely interested in the science and concepts behind learning different languages. I often find myself wondering why we haven't developed a single worldwide language. Its odd that, apart from already being multilingual or using translators, we can't even natively communicate with a majority of our own race. Do you think we will at some point develop a "worldwide" language? Also, apart from personal cultural interests, is learning a foreign language even worth the time with the technology we currently (and will) have?
