Bad automation allows you to poke yourselves in the eye a lot faster; it is as simple as that. Computers are much faster at executing tasks than us human engineers. If we had the same set of operating procedures executing by a human versus script, the script will finish faster than humans, sometimes without the benefit of having a solid feedback look between procedures. The Internet is full of horror stories when someone presses the Enter key and immediately regrets it.

We need to make sure that the chance of a bad automation script can go wrong is as small as possible.
