Culture is not only art. An LLM won't help you naturally drop you a "cuidao chacho que toy mu loco" nor "в жёлтом доме по тебе скучают", nor will it translate it into something that carries the exact meaning to you in English, nor reference any equivalent cultural element, for the foreseeable future. You'll need embeddings common life experiences, and even intonation can completely change the meaning even retaining the emphasis.

It will help you communicate, but not partake.
