To my understanding, the problem is that the nuances and subtleties of natural languages are not possible (or not as easy to convey) in artificial languages, for a number of reasons. This makes it impractical for real use: imagine diplomats having to speak their mind instead of beating around the bush :) But if you are interested in universal languages, I suggest you to check out Sol-re-sol [1]. I have read the story in Paul Collins' "Banvard's Folly" and have been fascinated by it ever since. [1] https://en.wikipedia.org/wiki/Solresol https://en.wikipedia.org/wiki/Solresol
