I'm assuming you watched the whole diavlog, which they called "Solstice Edition," my second choice for a title. My first choice was "Life with Robots," but I concede that would have been unfairly skewed to my side. Since they didn't use my title, I forgot that I wanted to say this diavlog has an official song. Here it is. (Or here, for low resolution.) [Low-res recommended if you at all think you might need it!]
If you can't take the time to watch the whole diavlog -- or have trouble getting through the scary fight at the beginning (which I unleash with the innocent question, "What's the deal with the right-wing conspiracy, Jonah?") -- at least watch the part about the robots. Then enjoy the song.
ADDED: Volokh Conspirator Orin Kerr links to the diavlog and gets a discussion going about whether someone promoting federalism today needs to pay attention to the way it was used 50 years ago. (In the diavlog -- and elsewhere -- I say they do.)
