what categories of concepts would they express to each other? maybe an identifier and some conditions like depth, water temperature or pressure, maybe some magnetic or gravitational field direction and locations, tides, topography, mating, food, distress, and then probably some concept of boats and types of boats.
All of those options sound interesting and plausible, yet when I go for a walk while talking with a friend, I'm imagining an alien anthropologist wondering, "Are they communicating the ambient air temperature, and the availability of food nearby, their orientation to the sun and Venus setting?" Maybe the whales are gossiping, or sharing old stories, songs, jokes...
like the weather, restaurants, and plans for the summer, or even breeding opportunities? (will admit to missing the subtlety of the joke tho)
maybe they're complaining about how the options on whale tinder are too blubbery, but he categories for living things to talk about are definitely shared, and dividing phenomena into them is pretty straightforward. the real risk might be that the next iteration of GPT simulates an always just out of reach imagined better option and whales stop reproducing in pursuit of it. we should try it on another species first.
Good point, yeah, generally the basic survival topics are still in play even when we're busy with finer details! Still, giving an intelligent species the credit for (perhaps) engaging in the final details seems like something generous to leave on the table! Like whale dating apps, exactly.
Maybe the trees would show something useful to GTP
