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?
