In the comment section here: Why don't Agents take over people before they swallow the red pill? I was told that it isn't possible for someone to know about the nature of The Matrix and still continue to live inside it. This phenomenon is apparently called "popping". This makes sense in terms of the plot of the movie. However, I'm curious about what the actual mechanism behind this might be. Is it that The Matrix just reads all your thoughts and determines you know and kills you? Or is it something intrinsic about the people within that causes this, not requiring any monitoring?
And what about someone who strongly suspects that it is a simulation but doesn't know other details about the outside world? What about someone like Elon Musk who says there is a 1 in billion chance we're in base reality?
