Demis Hassabis:  The thing I’m most excited about is I think we’re on the cusp now of a new era in scientific discovery, where we’ll be able to use AI and machine learning to help us in areas of science and medicine, to make sense of enormous amounts of data that we’re generating from our experiments, and find new insights and new structure in that vast amount of data.  I think that will lead to new scientific theories and new scientific breakthroughs.
