task 2, Will we ever... talk to the animals?

May be, to talk like humans, I think.... no.
But we can communicate with them through signals and different sounds, I think ... yes!!!. but we have to note that comunication could be created but with a specific meaning for example, in linguistic, we saw something related with this topic, "animals and human language", inside of unit we have "displacement" I take one part of it; "When your pet cat comes home and stands at your feet calling meow, you are likely to understand this message as relating to that immediate time and place. If you ask your cat where it has been and what it was up to, you’ll probably get the same meow response. Animal communication seems to be designed exclusively for this moment, here and now. It cannot effectively be used to relate events that are far removed in time and place. When your dog says GRRR, it means GRRR, right now, because dogs don’t seem to be capable of communicating GRRR, last night, over in the park. In contrast, human language users are normally capable of producing messages equivalent to GRRR, last night, over in the park, and then going on to say In fact, I’ll be going back tomorrow for some more. Humans can refer to past and future time. This property of human language is called displacement."
That will be the big different between humans and animals communication.
