If human beings are truly able to "talk" to primates via sign language, then will the day ever come when we can talk to our dogs, cats and horses?

This question may appear to be somewhat whimsical, but it’s seriously asked, because I feel that if a human being can indeed talk to a gorilla, then it seems to me that it’s only a matter of time, before we will be able to carry on a conversation with other animals also, and in a way, I’m almost scared of what they may say to us, about us.
