What happens if all your sensors fail, including the one that senses the failure of your sensors? What happens if the power source disconnects?

Having all your sensors fail is actually a very easy case. Imagine if all of your sensors failed: suddenly you could not see, hear, feel, smell, or taste... do you think it would be hard to tell that something was wrong?

Having your sensors fail doesn't mean they're not providing data. It means they're not providing accurate data. In humans, we would call this hallucinating, and humans in fact cannot generally tell that they are hallucinating.

That is one possible failure mode. But you're right, it's not the only one.
There is an extensive literature on how to detect and correct sensor errors resulting from all kinds of different failure modes.
They seem the same to me. In fact, in 27 years you are the first person to voice this concern.

Could be, but that would be a publishable result. So... publish it and then we can discuss.
