It amazes me how much we already discovered about our brains, yet how little do we really know about it and how much more is to know. From a CS point of view it is also very exciting how current hot areas, like machine learning are closing on on the same questions from a different angle. Are we digital or analog? Is our self simply a reflection of an incredibly deep, recursive, emergent meta-structure or is there some ineffable underlying level? Or both or neither? :) Exciting times we live in...
