Have you seen the Black Mirror episode with the Uber-esque tech company? The CEO is trying to placate a man in crisis over the phone. The CEO's support team starts feeding him via Slack de-escalation bullet points from their psychological experts. The man, bewildered and frustrated at the mechanical responses, stammers at him, "Why don't you talk like a normal fucking human being?!" The CEO then drops the "systematic" approach and talks to him like a person, from instinct, the heart, or whatever. Now you'll say that's a system too, but at some point the system is so riddled with exceptions that it becomes indistinguishable from chaos or intuition, and no longer is a useful system that can be described in any explicit way.
