Not at all.
I believe just throwing a corpus of dolphin-dolphin vocalizations at an LLM will fall very short.
I quote myself again -- 'But that alone would tell us almost nothing of what dolphin dialogue means".
Note the emphasis on the word alone.
What needs to happen is to build shared experiences, perhaps with a pod and incorporate that into the ML training process. If this succeeds this exercise of building shared experience will do heavier lifting than the LLM.
Had you spent less effort in coming up with insults and used the leftover processing bandwidth to understand my position it would have made for a nicer exchange. For restoring civility to our conversation I indeed do not hold high hopes.
I suspect the experience of being a dolphin is stranger and more alien than we will ever know. This is a creature that employs its sense of sonar as part of how it understands the world, and has evolved with that sense. It will have concepts related to sonar and echolocation that we cannot grasp. We might be able to map a clumsy understanding of them, e.g. a dolphin cannot smell, it might be able to understand "my nose can taste the air", but is that the same? At least in humans with sensory deficiencies, there are parts of the brain that have evolved alongside the same senses that an unimpaired person has.
Maybe we could finagle an interspecies pidgin, but I wouldn't be surprised if we just fool ourselves for a while before we realize that dolphin language is just different. Even the word language brings along a set of rules and concepts that are almost certainly uniquely human.
There are tons of shared experiences and shared emotions. It's not like there's some hidden organism that we discovered are making noise from within the dark matter. These are animals in the oceans. Plenty of shared experiences and emotions. Dolphins have feelings. Anyway... let's agree to disagree. I fully support this project and am optimistic about its outcomes.
