For most of its history, artificial intelligence was invisible. It ran quietly behind search engines, credit scores, spam filters, recommendation systems — shaping our lives without ever speaking to us directly. AI was infrastructure. It was never a partner in conversation. That changed with large language models. For the first time, millions of people started talking to a machine the way they talk to a person: in full sentences, back and forth, about real problems, real ideas, real doubts. Not typing commands into a search box, but thinking out loud with something that thinks back. This is not a small shift. It is the kind of shift that deserves its own field of study — and that field is Aithropology.
