Arthur uses the <em>Wheel of Time<\/em> example: If you use Balefire to erase an enemy general who just gave a fatal order, the order was never given.

Perhaps the Great Filter isn&#8217;t nuclear war. Maybe advanced civilizations inevitably discover ontological, reality-editing tech and <strong>accidentally erase themselves from existence<\/strong>, leaving no ruins or history behind.
