without a body the brain won’t ‘work’, the brain is very much linked to the rest of the body, the fiction that we only need the head to ‘reanimate’ a person back to normal is just that, fiction.
wei Dai:”rebuilding/simulating the body to the level of detail needed to support cognition” yes,but how complex is the nervous system? which wire connects to which, or is that not important? seems to me that you’re oversimplifying..
very smart people have issues with CEV, example: http://lesswrong.com/lw/2b7/hacking_the_cev_for_fun_and_profit/
and as far as I remember CEV was sort of abandoned a while ago by the community.
and yes, you value humans, others in the not so distant future might not given the possibility of body/brain modification. anyway, the gist of my argument is that CEV doesn’t seem to work if there is not going to be much coherence of all of humanity’s extrapolated volition’s-a point that’s already been made clear in previous threads by many people-what I’m trying to add to that is to point out the overwhelming possibility of there being ‘alien minds’ among us before a FAI could be built.
I also raised the question that If body modification is widely available, is it ok to prevent people from acquiring an ‘alien’ set of morals, one that would later on be a possible hindrance to CEV-like proposals? how can we tell if its alien or not in the first place?
