A few weeks ago, Ivan Sutherland came to Washington University to give a talk to drum up interest in a new idea he is working on (Fleet, Infinity & Marina [PDF slideshow]). In my experience, most "old guy" talks aren't that interesting because they meander with long tangential stories about their children. Luckily, those were kept to a minimum and he had a good sense of humor too!
Now---interesting as the talk was---he suggested everyone read his only non-technical paper titled, "Technology and Courage" [PDF from Sun]. It took me until yesterday to read it, but it was certainly an interesting article. I recommend everyone read it.
