Steve left out data mining and machine learning from his presentation and Bezos spotted it. Is that an example of Bezos' smarts or just a silly omission on Steve's part? Steve keeps emphasizing how smart Bezos is but I see no evidence of it in this post. It just seems like Bezos is good at spotting obvious mistakes people make.
