An attempt at understanding dolphin language is being made — will people listen?

Since it was first published in 1979, Douglas Adams's The Hitchhiker's Guide to the Galaxy has seen generations of the philosophically minded expand on some of its themes. The series of books is comical, of course, as it satirises ontology, metaphysics, the pomposity of politicians, the dreadful diatribes of bureaucrats. But in all the fun of puns, Adams often stumbled into, perhaps knowingly, profound questions. The most popular of these is the Babel Fish argument — based on a creature that, by eliminating all boundaries to interspecies communication across the galaxy, caused the most dreadful wars of all. And then there's the enigma of dolphins. As the Earth is about to be destroyed in the first book, they leave the planet, leaving behind a one-line message: 'So long, and thanks for all the fish.' Now, as AI models threaten and promise to make the fears and fortunes of sci-fi worlds a reality, Adams's questions might just be answered.
This year, the Coller-Dolittle Prize — given for research into two-way inter-species communication — was awarded to the Sarasota Dolphin Research Program. It has used non-invasive methodologies to study the various vocalisations and body language of bottlenose dolphins for about 40 years. This data can be used to train AI models that can potentially uncover the layers of meaning in non-human language.
The dolphins in Hitchhiker's were smarter than human beings. And perhaps, for a given definition of intelligence, life can imitate art. For a long time, human beings have ignored the personhood of intelligent animals. Elephants, higher primates, dolphins and whales — there are several species that have language and heritage, that laugh and cry and grieve, have a sense of family, self and community. Perhaps AI can translate their realities in a way humans can understand them, and learn from them. But then, given that people are so adept at treating people as things, what chance does a dolphin have?
