According to my conception of consciousness, if my brain was to be copied and then destroyed the copy would still be me and I would still have this consciousness in all meaningful senses of the words. I mean, moving my brain an inch doesn't erase me, changes in my neural network and stuff don't erase me, why would this ?
This sort of stuff also led me to weird ideas. For example, my current opinion is that when you die, "you" (again, in all meaningful senses of the word) keep being conscious because thoughts that are like the ones that you have - or could have had - are still being had. Similarly, as you are having conscious thoughts, everyone alive or dead or other who had/have these sort of thoughts are partly "conscious" through you (through this brain activity). Consciousness - and identity - sort of don't exist as much or as strongly as we like to think they do, but in a way that makes it so that the "consciousness" that you have now is still going to be there when you die, it's just that it's not this brain that will be producing it anymore and the fact that "you" won't be there to experience it doesn't matter because it doesn't mean anything in reality.
Which brings me back to : what if being copied and destroyed wasn't really an issue at all ?
That stuff's really hard to explain. Still, thoughts, people ?
