Humans communicating with animals (in cases where that's possible) is only interesting or worthwhile because of how similar our brains are to theirs. We don't spend a lot of effort trying to communicate with more primitive animals. I'm not sure why an AGI would necessarily regard us more like chimpanzees than lungfish. If we could talk to a lungfish... what would it say? Is its perception of the world even sophisticated enough for it to matter?

And to be clear, I'm actually not an AI catastrophist. I just don't think any sufficiently advanced AI is going to be very motivated to help us with our puny problems. I think it's more likely they'll just fuck off somewhere far away where we can't bother them.
