U.S. Soldiers Recipients of Newest Prosthetic Technologies

plaastik writes "The next generation of naturalistic and touch-sensitive artificial limbs are being worn by U.S. Soldiers.

From the article: 'Future prosthetic arms will fuse to existing bone, eliminating the need for awkward attachment systems. These more naturalistic limbs will use bionic nerves attached to natural nerves to send and receive signals from the brain. Chips embedded in the user's brain will help command artificial-muscle-activated, touch-sensitive, fully articulating hands.'"

    When does someone stop being human [...] What of the soul?

    Perhaps you can first provide a concrete, evidence-based definition of what a soul is, then we can have an intelligent discussion about whatever it is.

    When does someone stop being human, once we can replace their body with a machine?

    There is a very funny, insightful, and interesting (and informative too) short SciFi story by Stanislaw Lem on this subject. In it the protagonist (?) — a racing car driver, or something like this — is being sued by the protheses-makers to return the parts, because he defaulted on the payments...

    Lem wrote it in Polish, and I read it in Russian, but there is, no doubt a translation available for your preferred language. Look for it. Lem is one of the greatest SciFi authors... Whatever you find (almost) will be worth reading.

    Now, in the story even half of the guy's brain is artificial (and has a slight defect, causing him to count everything he sees), which really does make the question asked by the parent meaningful. But we are not there yet, and can not replace the brains, so the answer is rather obvious...

    I wonder if proper body and vehicle armor is cheaper than prosthetics, multiple surgeries, psychological counseling, and a lifetime of subsequent health problems. I also wonder what these soldiers lost their limbs for. Iraq and Afghanistan aren't exactly basions of freedom, are they? Yes, they'll be peaceful one day in the future, as will the entire earth when the sun runs out of hydrogen. I do realize that every time a flower blooms in Iraq it's because of American resolve and committment, while none of the death and destruction is our fault, but still, one wonders what the hell it's all for.

  5. Mixed Tense Confusion by fbg111 · · Score: 5, Insightful

    Note to editors, keep your tenses consistent. The headline and abstract use both present and future tense, and without reading the article I can't tell whether these technologies are actually in use now, or will be in the future. It seems like just a few months ago that monkeys were controlling robotic arms with just their brainwaves, has technology advanced so quickly that we can now physically and neurologically integrate electronic machines with people? The article confuses that crucial point.

    "Why not just let those imperialistic fuckers rot in some hospital bed?"

    Here's a serious question for idiot leftist /.'ers whose hatred of America and it's current government matches that of idiot right wingers hatred of Islam and yourself:

    What are you leftist /.'ers actually doing, apart from complaining and bitching, to make things better?

    Seriously, left-leaning ideological /.'ers have turned this place into an anti-american soapbox that mirrors the intense hatred of sites like LGF and FreeRepublic, but I have yet to see any of you do anything about it. Where is the organisation for making things better? Where is the supposed open source community (you know, works in the open) spirit applied to political community?

    All I see is bullshit statements like your own with little action.

    This place is really beginning to stink.

    Gah! Dilemma!

    On one hand, you're bringing religion into a discussion about technology. My initial urge is to stare at you blankly until you go away, or yell "keep your religion off of my science", or tell you that if you object you don't have to take part but you shouldn't tell other people how to live, blah blah etc etc. Most likely, I just wouldn't respond at all.

    On the other hand, you correctly used "raises the question" instead of incorrectly using "begs the question", for which I want to applaud.

    What to do, what to do....

    Anyway, your statements were:

    When does someone stop being human, once we can replace their body with a machine?

    There is an old thought experiment that goes something like this:

    "If you could replace a single neuron with a device that responds exactly the same way, would you be less than human? All input to that device is the same, all output is the same, for all the neurons around it, absolutely nothing has changed. Now, imagine that you start replacing every neuron, one by one. After each replacement, for the natural neurons around it, still nothing has changed. When you are finished, you have a functioning brain that continues to process all input exactly the same as before, only now it is mechanical instead of biological. Now is it less than human? If not, at which point did it change into something else?"

    It's an interesting problem, and if you are as intelligent as you seem, you can ponder it out without me contaminating your process with my opinions.

    Is it just the brain?

    Yup. I hope that wasn't a surprise.

    What of AI then?

    It depends on what you mean when you think of the term "AI". Like so many other terms, it has partially lost its original meaning due to overuse. By the very definition, though, it is artificial. A computer program designed to fool humans is not true intelligence. A computer program that emulates probable human responses is not true intelligence. Ah, but what if, similar to the above thought experiment, we could somehow copy a person's neurological responses... and put that data into a program that would simulate a complete working brain, down to the last neuron. Would =that= be true intelligence? Hmm...

    What of the soul?

    What of it? If you believe in such things, good for you. However, there has never been any scientific evidence* that such a thing exists or exerts any force over my choices or actions. So, I'm comfortable living my day to day life without such worries. YMMV.

    *For those that would respond "Absence of evidence is not evidence of absence" (which is a true statement), I would say "No, but it sure is an =indication= of absence." But as Carl Sagan said, "You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe"
