I enjoyed the talk very much, especially the part towards the end about management and how people whose sole job is to manage are a large problem because they start making shit up to manage because they need to fill out an eight-hour day. I think he does make a logical error about b-school, for example, in saying that because customers don't care whether you did the 5 forces analysis or not such analysis is irrelevant. B-school probably has tools such as 5 forces that may help you build a better product or position it better and just because your customers don't see or care about that analysis does not make it irrelevant. Kind of like building a web service on ROR.
