Is the modern definition any different than the older one? It just means systems with feedback loops. A motion sensitive video camera is “cybernetic”. So is the Facebook feed algorithm and self-checkout at the grocery store.
If you read old cybernetics writing it’s hard not to see a striking analogy with the excitement around machine learning. They had all kinds of medical experiments showing the usage of feedback mechanisms on the body and brain and how they were just on the edge of unlocking artificial humans.
