You can take a human organ out and put it in another human as long as the parts match.
Except for the all-important one: full brain and/or head transplants.
We can't remove our consciousness and toss it into another vessel.
not yet we can't, but eventually...
. All we are is a series of firing synapses in a specific pattern, who is to say that eventually we won't be able to take a snapshot of the brain activity, remove the brain transfer it and restart it with the same brainwaves, I would argue that qualifies as a transplant we just can't do it yet as far as I know. killing the geth is genocide.
Edit: damn, ninja'd:bandit:
That idea is appealing as, in effect, you would have acheived immortality. Why not save that brain image somewhere and download it again if you are killed? I'd be all for it. But, as neat and tidy as the process sounds it appears that the technological limitations would be hard to overcome. At least in the real world; I suppose you could argue that the Lazarus project probably has alot of the necessary technology.
The first technical difficutly would be understanding the brain well enough to develop precision equipment to 'scan' the brain and record the motion and location of every atom. Next, you would need equipment that could store this ginormous amount of information. It would probably require exponentially more space than all the storage devices we have today. Still sounds feasible as we can assume there will be major computing advances in the future.
But, then, you run into the issue that our personalities are also a function of each unique brain. Some brain abnormalities cause major personality shifts. If your brain has, for example, a minor genetic abnormality you'd need to have an exact copy of your physical brain with the abnormality for the downloaded information to recreate your personality. So, I guess we would need to develop cloning and make sure to exactly replicate the brain with every abnormality. Even then, you run into the question of whether you would even want to recreate an abnormality. I guess, it depends on whether it causes harmful or beneficial personality issues. In any case, if you don't recreate them are you even you? Is a person that suffers head trauma with resulting major personality shifts still the 'same' person as before?
Next, we run into the issue of our body's effects on the brain. Some research shows that the flora in the gut may effect mood. Do you take samples of that flora and recreate it? And, this is just one example. How many other unknown non-neural biological processes do we need to take into account?
Finally, we run into the problem of exactly what is consciousness? I'll just go ahead and dismiss the idea of a soul as I see no evidence to support that concept. Is it an emergent property of the brains' physical processes? We don't really know at this point although it is being studied. This, more than anything, needs to be understood before we even think about tinkering with recreating individual consciousness.
It boils down to 'what makes you, you?' The only way I can explain what I mean is to give an example similar to the 'transporter problem'. So, say, all the technological limitations are overcome, you are killed, and your brain scan is downloaded into a new brain. How are you sure that
you will wake up and not just a copy of you? What if you are still alive when the download takes place? There is now a new and orginal you. It is not possible for you to experience the reality of both individuals. This thought experiment tells me that only a copy of you can ever be acheived and that once the original you is gone, you're gone. Unless of course, we learn something new and unexpected about the nature of consciousness.
