Did you read Chaos Monkeys? What about Dragnet Nation? Both (of which are not new) peek behind the curtains you're concerned about. Both are recommended, and freightening. It's only going to get worse.

Borrowed Chaos Monkeys from the library based on this post. Thanks for the recommendation, it's very engaging so far.

And yes, his style is very entertaining. I hope you enjoy it.
