Comment by squeegily on Caelum est Conterrens: I frankly don't see how this is a horror story · 2021-01-28T23:56:17.391Z · LW · GW

I think I've solved it:

Yudkowsky had read Friendship is Optimal, a soft-horror story detailing a plausible outcome of Hasbro-sponsored [F]AGI. This story is roughly the origin of the so-called "Optimalverse" in which Caelum est Conterrens is set. The latter links to the former for context, so I imagine that he simply got the 2 confused (or even forgot the latter) when compiling links from his browser history for that write-up.

(If I only remembered FiO, I'd certainly have pegged it as “Caelum est Conterrens” if you asked me offhand; in fact, I'd just as likely mismatch the titles even if I did remember CeC, if I hadn't burned the which-is-which into my memory by contemplating the confusion you're expressing by this post.)
