> There was a post on HN a while ago which basically was about how using language (and probably, speaking out loud) is actually a `feature' or `technology' of human mind Really would like to see that post, as I've been vaguely interested in this very topic for quite a while. Is there a chance that you remember any key words that might've been in the title, so I could plug them into the HN search? From what I gathered so far, one hypothesis is that language development went hand-in-hand with both consciousness and empathy, i.e. social cognition: as we learned to see the world from the viewpoint of others, we also expanded the abilities to communicate with others and think to ourselves.
