This is a phenomenal book, despite starting off slow. The authors' attempt to link Moore's pioneer heritage to his intellectual and professional drive falls flat. But that's ok.
Moore is seriously underrated, particularly as compared with Andy Grove. Moore combined intellectual discipline and ability with entrepreneurial character in a way that, I think, is seldom seen. Moore's status should be raised. His life story is interesting, and the description of the infancy of Silicon Valley is interesting, but the book is strongest when describing Moore's insights into the manufacturing process and technology. The authors describe the mechanics of Moore's Law, which was about the intersection of returns to scale and learning by doing. The book also provides insights into the role of the US government in the development of the semiconductor industry, specifically on the demand side. People typically think of government's role in R&D as being about subsidies of various sorts, but it appears that simply providing large demand was the key role. That is what allowed for the scale that drove Moore's Law. War drives everything, in this case the Cold War.
I recommend the book.
