The danger of repeating signals
Kevin shares this great quote from the Count of Monte Cristo:
"I have been told," said the count, "that you do not always yourselves understand the signals you repeat."
"That is true, sir, and that is what I like best," said the man, smiling.
"Why do you like that best?"
"Because then I have no responsibility. I am a machine then, and nothing else, and so long as I work, nothing more is required of me."
