The IEEE Spectrum "special report" on The Singularity makes for interesting reading, but I’d like you to try something as you click through it. When you read these essays and interviews, every time you see the word "Singularity," I want you to replace it in your head with the term "Flying Spaghetti Monster."
(My personal favourite right now is "The Flying Spaghetti Monster represents the end of the supremacy of Homo sapiens as the dominant species on planet Earth.")
The Singularity is the last trench of the religious impulse in the technocratic community. The Singularity has been denigrated as "The Rapture For Nerds," and not without cause. It’s pretty much indivisible from the religious faith in describing the desire to be saved by something that isn’t there (or even the desire to be destroyed by something that isn’t there) and throws off no evidence of its ever intending to exist. It’s a new faith for people who think they’re otherwise much too evolved to believe in the Flying Spaghetti Monster or any other idiot back-brain cult you care to suggest.
Vernor Vinge, the originator of the term, is a scientist and novelist, and occupies an almost unique space. After all, the only other sf writer I can think of who invented a religion that is also a science-fiction fantasy is L Ron Hubbard.
