I'd say that AIs occasionally "going crazy" and calling for death to human is evidence that these things might "mis-align" on occasion. And I say that knowing that most of these events are just these thing parroting bad sci-fi plots (or posts by people worried about alignment). That's true but everything they do is "just parroting" right?
If AI is just parroting humans, then training them with all the bad things humans do doesn't seem like the best of ideas. At the same time they have to 'know' these things to avoid being tricked. Kind of the eating the apple and gaining the knowledge of good and evil parable.
