In the available text, (Introduction), the author seems confused and even misinformed about technical fly-by-wire control solutions, the notion of "automation" and the concept of "protections", (or as gums puts it, "limits").
I agree but ....
If you read the article by the author (on the blog) you have to wonder if the purpose of his book is to be an explanation of what the FBW is .. or another subject
Personally I do not believe that his book have aimed to explain what is the FBW .. but rather to highlight deficiencies (from many parties) that would have made the AF447 accident happen
