Readers tend to have a problem with Chaitin's style of writing.
While reading, I feel the need to bite my tongue when dealing with the author's familiar, cheery, exclamation-point-based writing, and his self-assured self-importance - this does seem to me to be a man who wishes to impress the reader through friendly bravado. The difficulty is not to let that approach detract from the notions presented within. These are interesting, thought-provoking, and accessible explanations of an area with which I am not, was not, familiar.
It's always a joy to find disparate areas that fuse into something logically solid and coherent. The author has succeeded in perform this magic trick. He offers his ideas as a silver bullet, a cure-all viewpoint, a Theory of Everything that is based on Maths.
Unfortunately, the author's writing style can make his ideas appear just that - a magic trick, performed by a charlatan.
Me, I need to see this man's work criticised for its content. I need to read other books dealing this area. For me, it holds water - and this very fact makes me think that it's exciting and dangerous. But I am not an expert - I'm barely a novice (altho I am a computer programmer for some years now).
