actually, it's theoretically a hard problem -- https://aclanthology.info/pdf/J/J86/J86-4003.pdf https://aclanthology.info/pdf/J/J86/J86-4003.pdf I would have thought that they needed to 'ground' (https://en.wikipedia.org/wiki/Symbol_grounding_problem https://en.wikipedia.org/wiki/Symbol_grounding_problem) at least one shared reference word/concept so they could proceed to define everything relative to that and thereby communicate effectively and know how to map different languages to the same latent space.
