I agree completely. He was making an analogy for Watson about the intensity he liked to focus on his own subjects. I have people like this in my family. They are very focused. Not wanting to learn things that do not interest them. I have a brother in law who doesn't drive because it is not worth his time to learn. He just isn't interested. He runs his own computer software company. He is also Aspergers. These very focused and single minded people can seem quite helpless and clueless when faced with ordinary things we would think everyone should know. My 11 yr old can tell you all day about his interests, but I can't get him to memorize our phone number and home address. I don't think these TV tropes are all that off from these types of individuals. I suppose because I have people I love who are like this, I find them endearing and charming most of the time.
