You then asked why those cases weren't also Y. I pointed out that computers aren't always also Y, so why did you think that humans with X must also be Y?
I am not implying a global watchdog, for the simple reason that distributed computing systems can have local watchdogs which reset a node when the node is not active, even without global intervention.
The mechanisms can be different - animals swim while submarines don't, but both move underwater. My point was that I disagreed with your intuition and conclusion, and since I can find one counter-example to show that X doesn't imply Y, you can't conclude that X must imply Y. Nor can you conclude my counter-example is the only possible mechanism.
You still haven't described the basis for your intuition.
