As a response to the popular idea of the Singularity—the nerd-Rapture-like idea that at some point in the future, science will be able to upload our consciousness to computers—Dvice has composed a list explaining why that will never happen:
This may seem like a cheap shot, but "uptime" is something our most advanced computer scientists still struggle with. Hell, our super-sophisticated algorithms can't even keep a text-based microblogging service from crashing during the World Cup — what happens when there's a Fail Whale for your mind? Will it be like getting a hangover, having a stroke, or dying? You'd have to assume we'll all be "backed up," but that raises troubling questions too: when the server running You goes kaplooie, is your "backup" really you, or just a clone of you that takes your place now that the "real" you is lost? The Singularitarians don't have reassuring answers, and I don't want to find out the hard way.
(Also, if a Swedish kid torrents your brain, will that copy of you talk like a pirate?) In any case, I love that we are at the point where someone feels the need to pooh-pooh the idea that we'll all be digitally immortal someday soon.
