Well, I’m surprised that there are only three noted here, given that the idea crops up regularly in science fiction and â€œtechnoprogressiveâ€ (e.g. transhumanist) writings. Still Yudkowsky does highlight three significant ways in which technoprogessives see accelerating technological change generating a ‘point of no return’. I’d want the apocalypticist viewpoint developed more – there is definitely a religionist stream to some of the singularity talk (even if that’s denied by some) and far more nuanced negative critiques have been put forward.
