Artificial languages don't succeed for obvious cultural reasons. Here's a short (and, by all means, not at all comprehensive) list of the prerequisites for an artificial language to replace English as a world language:
1) It must be a native language of at least some countries (and preferably of countries that are powerful players in international politics and decision-making *wink, wink; hint, hint*).
2) A colossal amount of cultural international export must be available and acceptable worldwide (i.e. movies, songs, etc.) in this language
3) This language must be the Internet language.
4) There must be ready translations of all important bibliography (both fiction and non-fiction) for this language
Can you spell impossible?
