Can artificial intelligence really help us talk to the animals?

A dolphin handler makes the signal for "together" with her hands, followed by "create". The two trained dolphins disappear underwater, exchange sounds and then emerge, flip on to their backs and lift their tails. They have devised a new trick of their own and performed it in tandem, just as requested. "It doesn't prove that there's language," says Aza Raskin. "But it certainly makes a lot of sense that, if they had access to a rich, symbolic way of communicating, that would make this task much easier."
