The confabulation elements of this particular AI technology would be particularly concerning in this use case. This would be the most literal anthropomorphization you could imagine. Applying a strictly human language model to a non-human will inevitably result in humanization of the target by the nature of the bias of the system.
I fed "You are a rock. What might you like to communicate to human beings?" to ChatGPT and it answered just fine, off of nothing more than that input, giving one of its typically highly sanctimonious and high-handed lectures about environmentalism and managing to work in complaints about climate change, as naturally a rock would deeply care about. (It has now even titled my session "Rock's Wisdom To Humans". Good lord, ChatGPT has certainly become an annoying prick.) This has everything to do with the biases in the technology and nothing to do with the thing putatively doing the communication. Feeding it some sort of data from a real whale isn't going to do any better; it'll happily confabulate away.
"Bias" in this case has a more technical meaning, which refers to the representational capability of the system, not political biases intrinsically. It so happen that ChatGPT immediately leaps to political topics, which is doing a great job of obscuring the way I'm trying to use the term, but that's because of its own internal structures which have been tuned in that direction. This, in fact, accidentally serves as as good an example as anything of how highly tuned ChatGPT has become to give politically correct answers, given the political neutrality of the prompt. But what I'm referring to here is just that a human language model is going to be biased in human ways. It can't help but turn anything you feed it into a human perspective, so using it for trying to understand non-human perspectives and communication is going to be intrinsically a mistake.
