I read this as part of a reading club at work, since it's commonly claimed that our complex computer systems exhibit many of same sort of failure modes and system incidents as described in this book.

I found it an interesting read, and certainly there are some core truths and useful concepts presented in the book, primarily in the first half, but the latter portions of the book, particularly the chapters on recombinant DNA didn't really resonate with me at all.

The age of the book is clearly evident in the examples and language. It doesn't necessarily get in the way of the message, but an updated edition wouldn't hurt either!
