Fun fact: if you pause the video and click to different random points, you get to look at a random sampling of Wright's facial expressions, which oscillate between frustration, exasperation, and red-faced rage. Eliezer's expressions move between neutral, amused, serene, and placid.
I agree that Eliezer maintained his calm better, but I don't believe that Wright is the simpleton you seem to be painting him to be. I've watched a lot of his videos, and I would say there are very rarely moments of "red-faced rage," and certainly none in this video. He was at times frustrated, but he really is working to understand what Eliezer is saying.
Sweet, there's another Bloggingheads episode with Eliezer.
