The problem with Esperanto is that it isn't easy to learn. It's easier than French and English, but for anyone who grew up in Asia for example it's actually quite difficult because of it's European bias. See http://en.wikipedia.org/wiki/E...

We already have primates that can communicate with humans in a human language (American Sign Language or something similar) at the level of a child.
To be clear, when you say "child," that means a 2-3 year old. They never (after a lot more than 2-3 years) get past simple two word sentences. It's not clear they're even doing that. Since they never demonstrate any understanding of grammar, it's almost impossible to show they're not just learning tricks to get a desired result.
