Currently reading the book, and could see the zealotry come out, but they mention, repeatedly, that your own systems may not need the level of service that Google built-in, or your teams may not be big enough to justify, etc. I don't think it is quite fair to indicate that they didn't give that thought. I totally agree that it is a great book and should be encouraged throughout ops orgs, devops roles, and developers who want to plan for the future, but that not every company needs the Google way to 100%, or maybe even 50% (as you indicated as well).
