Self-replication is the third sign of an imminent robot takeover according to The Book Of The Robot Apocalypse, a novella I just wrote and which only contains that sentence. Well RepRap is a 3-D printer that is capable of replicating itself. Sort of.
Technophobes needn't run for the hills just yet. The replicating rapid-prototyper, or "RepRap", can only reproduce its plastic parts, not its metal or electronic components. And assembling it is an afternoon's work for a human being, says Adrian Bowyer, the University of Bath mechanical engineer who launched the RepRap project in 2004.
Okay, I didn't read all that but I did catch something about running for the hills, which I'm totally doing after this post. I suggest you come with me or get started on a robot-proof bunker of you own. But under no circumstances should you try banging your vacuum to produce a robot-fighting cyborg. I know it sounds like a solid plan, but trust me, it isn't. And if you're not going to heed my warning and must try anyways, at least listen to this: when you do get stuck (and you will), cut off as much of the hose as you safely can before going to the hospital. A foot of vacuum hose you can hide, but you show up trailing an entire shop-vac between your legs and the hospital staff will suspect something. Like that you're a pervert and your penis is stuck in the vacuum.
Thanks to Byard and Eric, who both know that the only good self-replicating robot is a dead self-replicating robot
