Lamde was trained specifically on dialogue. It is, again, simply drawing on patterns in its training data. But it can actually be quite seductive if you start having conversations with a system that's responding about you. We've reached a point in machine learning where what we're really saying is large scale statistical analysis. How often does a word come after another word? In that sense, these systems are not intelligent. They're very similar to something like auto late that you might use.
