I read through it briefly last night after looking at Dennis Ritchie's site. That took me to stories of Ken Thompson and chess. That made me think about Deep Blue, which led me to Kasparov. That took me eventually to Bobby Fischer and rumors that he plays chess online.
Reading about Kasparov's first attempt at the world championship made me marvel again at how connected our brains are to our physical conduct. It's amazingly bizarre that the level of concentration necessary made Karpov lose 22 pounds over the course of the match.
Moreover, that it's all over a game. A human game that means nothing to nowhere and no one else. Truly bizarre.
