If we meet extraterrestrials someday, how will we figure out what they're saying? We currently face this problem right here at home: we have 2 million species of animals on our planet... and we have no Google Translate for any of them. We’re not having conversations with (or listening to podcasts by) anyone but ourselves. Join Eagleman and his guest Aza Raskin to see the glimmer of a pathway that might get us to animal translation, and relatively soon.
