The relevance of cybernetics to design and AI systems

“Cybernetics is the science of feedback, information that travels from a system through its environment and back to the system. A feedback system is said to have a goal, such as maintaining the level of a variable (e.g., water volume, temperature, direction, speed, or blood glucose concentration). Feedback reports the difference between the current state and the goal, and the system acts to correct differences. This process helps ensure stability when disturbances threaten dynamic systems, such as machines, software, organisms, and organizations.”

“Simple feedback systems have goals imposed on them. Second-order systems, which observe themselves, may adjust their goals. Second-order systems don’t just react; they may also learn. When two first-order systems engage, the result is interaction. They push each other. When two second-order systems engage, the result may be conversation, an exchange about both goals and means. As discourse on cybernetics expands to second-order systems, issues of ethics emerge.”
