What happened to cybernetics according to the notes?

• A. It became the dominant paradigm in cognitive science
• B. It was killed by artificial intelligence, but made a comeback with neural networks
• C. It evolved into modern machine learning
• D. It vanished without a trace

Answer: (B)

Cybernetics focuses on feedback, control, and information processing in both machines and living systems. In the notes, its early excitement waned as artificial intelligence research shifted toward symbolic, rule‑based approaches, causing cybernetics to lose prominence for a time. Later, the rise of learning-based methods—especially neural networks—brought many cybernetic ideas back into play, as systems increasingly exhibited adaptive behavior, self-regulation, and learning from data. That historical arc is why the description that cybernetics was sidelined by AI and then revived by neural networks is the best fit. It wasn’t that cybernetics simply became the sole paradigm in cognitive science, nor that it neatly evolved into modern machine learning on its own, nor that it disappeared completely.
