If you're a normal person, the fact that you shrug your shoulders when faced with such things is beneficial because shrugging your shoulders instead of being heroic when faced with the destruction of civilization serves as immunity against crazy ideas and because you're running on corrupted hardware, you probably aren't as good at figuring out how to avoid the destruction of civilization as you think.
