Marshall Brain's writings like Robotic Nation and Manna have inspired my own work. I made my own video version of the concept around 2010, as a parable called "The Richest Man in the World: A parable about structural unemployment and a basic income." (I also pulled together a lot of links to robot videos in 2009.) It's great to see more informative videos on this topic. CGP Grey's video is awesome in the way he puts it all together.
