Strange, I read it and had the opposite reaction. With the exception of the 'steel mill' quote you mentioned, I think he got it mostly right. Even that can be argued to be right to a degree, for a time the mainframe model was in vogue and now we're moving towards the 'cloud'. The little change mentioned between 1913 and 1967 was with reference to the overall trajectory of industrial economies, not technological innovation.

The main thrust was about the increasing importance of knowledge and information, where he was spot on.
