Jim Gray was recently interviewed by The Register about the use of GPUs for processing data and the challenges for coding parallel systems.

Every interview, whether written or video (http://channel9.msdn.com/ShowPost.aspx?PostID=49891, http://channel9.msdn.com/Showpost.aspx?postid=50428) Jim comes across as being immensley intelligient as well being clear and concise.
Being called a Distinguished Engineer just about sums it up.
