Will we build an audio system before 2040 that facilitates a nontrivial two-way exchange of information between humans and a dolphin or sperm whale (or any Cetacean). This market aims to have a high bar for what would qualify as a meaningful exchange.
Some examples that would resolve YES:
We build a system that can communicate the steps of a complicated trick or maneuver using an audio system alone to a dolphin. The dolphin attempts the trick, and we provide audio feedback about what it might have done wrong. In less than 3 rounds of feedback, the dolphin does the trick correctly
We negotiate a trade between ourselves and a dolphin, asking what we must offer in order for it to complete an unfamiliar and nontrivial task. The dolphin responds vocally with a request that we can confidently interpret, then performs the task after the request is met.
On an I-know-it-when-I-see-it basis, a conversation more conceptually broad and substantive than one can have with a typical two-year-old human
