I'm excited by any research that brings our understanding of animals closer to that of humans. Switching from human-centric (if it doesn't match how humans do it, must not exist) to species-first analysis over the past few decades is getting us closer.

Decoding the basics of an existing animal language is an inflection point I hope we hit soon, which should lead to regular discoveries. We almost always assume each individual exists in a vacuum; so much can be gained once a few verbal cues click.
