I can understand why scientists, linguists, and whale enthusiasts might be interested in understanding whale communication. But I have a much harder time imagining that whales have much to say to humans other than, "Please kindly fuck off" in 99% of cases.
It might be true that the filter feeder whales are better at feeding themselves than we are at feeding them. But probably not.
For the predatory whales, it's definitely untrue.
The reason dogs live with humans is that it's easier to have their problems solved by the humans than to do it themselves. That's why the phenomenon continues and why it began.
