language is much more 00:12:18 complicated than is often presented it's to me the primary unit of language is not the sentence or the word it's the conversation I think that we didn't have language in the archaeological record 00:12:31 until we had a conversation symbols were the beginning but symbols would never have arisen outside of conversations they could have only come about in conversations so we have meaning and 00:12:44 lexical meaning phonetics the history of languages grammar psychology culture on top of all of that so language is quite a complicated thing which is one reason I'm not worried about robots learning 00:12:57 language anytime soon they would have to at least be able to learn culture at the same time
