Not everything is about AI and direct existential risks.

For instance, the first thing that comes to my mind in this space is effective rationalist memes becoming coupled with evil, or just insufficiently-thoughtful and ethics-challenged, ideologies or projects, creating dangerous and powerful social movements or conspiracies. Nothing to do with AI and not a direct x-risk, but something that could make the world more violent and chaotic in a way that would likely increase x-risk.

I upvoted the OP and think this topic deserves attention, but share JoshuaZ's criticisms of the initial examples.
