Re-reading that post, I came upon this entry, which seems particularly relevant:

We're all living in a figment of Eliezer Yudkowsky's imagination, which came into existence as he started contemplating the potential consequences of deleting a certain Less Wrong post.

Assuming we can trust the veracity of this "fact", I think we have to begin to doubt Eliezer's rationality. I mean, sure, the Streisand effect is a real thing, but causing Roko's obscure thought experiment to become the subject of the #1 recently most read article on Slate, just by censoring it? Is that really realistic?

...

Seriously, did anyone actually see something like this coming?
