> This book intends to be a little guide about how to be the Erlang medic in a time of war. It is first and foremost a collection of tips and tricks to help understand where failures come from, and a dictionary of different code snippets and practices that helped developers debug production systems that were built in Erlang.

The introduction is a real help to explain the why of Erlang to non-technical people.

Are you referring to this bit?

> Erlang is a programming environment where the approach taken is equivalent to the human body’s immune system, whereas most other languages only care about hygiene to make sure no germ enters the body.

That is a very good way of describing it actually. We accept the fact there are going to be errors/diseases and build systems which can protect themselves against them.

The whole introduction is gold. It explains why and how Erlang is different in an understandable way.
