Favorite talk so far

Granted the conference pretty much just started, my favorite talk so far was Stephen Muggleton's talk on computational biology. I was especially interested in the idea of the robot scientist and using ILP for systems biology. He said that he hoped his talk would provide inspiration in the field, and I thought it did. I really bought in to what he was saying about how it's an exciting time for AI because we can apply our tools to this very interesting domain of biological/chemical research that has tons of data and tons of real world applicability. Anyone else seen a talk they really liked so far?
