Elon Musk seems to repeat the stuff that ran around lesswrong quite often. And I'm sure some of the people investing on AI right now are afraid of Roko's Basilisk. And of course there's plenty of references to Yudkowsky, either knowingly or not (ironically, I've never seen anybody talk about that MIT study that created the Yudkowsky's timeline).

But that's it. I don't think there's more cultural references to be found.
