I don't think it has already been posted here on LW, but SMBC has a wonderful little strip about UFAI: http://www.smbc-comics.com/?id=3261#comic
It's a repost from last week.
Though rereading it, does anyone know whether Zach knows about MIRI and/or lesswrong? I expect "unfriendly human-created Intelligence " to parse to AI with bad manners to people unfamiliar with MIRI's work, which is probably not what the scientist is worried about.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
