Demis Hassabis: So I dedicate my life to, you know, artificial intelligence — which is obviously what we do at DeepMind — but really, the underlying reason I work in artificial intelligence is I want to understand how the universe works.  And I want to, you know — it’s the deeper scientific question.  I want to try and answer the most deep questions that we have: What is consciousness?  What are we doing here?  What’s the universe about?
