It all comes down to "well, sure we might have plenty, but if not for capitalism how could we decide how to divide it?"
But any solution has to promote self-interest as a virtue and can't take things away from people who currently own them, and also must conform to a bunch of myths we have about "how the world works"
I think it is obvious to a lot of people, but still worthwhile
First, the idea "humans are super special" is deeply ingrained in our science and cultures. It's dying a very slow death, and each new study like this further shifts how we see nonhuman life, and ourselves
Second, studying how to establish mutual communication with animals is how we learn to do it better. Coming up with efficient training methods to teach communication is useful in a practical way
This is a small step with unsurprising results, but it's a small step forward
