Esperanto was supposed to be the "New" universal language. It was logically laid out and endorsed by the UN. It has gone nowhere. Much like Klingon,
only a few fans speak it. Most people stick with the language of their parents and never bother to learn anything else. Trying to get the whole world
to learn only one language, is unlikely to happen.
My parents only spoke one language while I speak three languages, and a bit of several others, and am a rarity in the US. Many people I know cant even
speak English correctly.
