^ I'm just going out on a limb here and assuming that there's a HELL of a lot of difference between things like eyeglasses, replacement hips, COWS, etc. and completely altering the structure of the body and mind. Getting a new hip, or even limb, doesn't change the way people think or act.
And you didn't answer my question: all those life-changing technologies you spoke of, like instant cloning, consciousness transfer, nanotechnology, etc.,
what happens to those who choose not to use them? You speak of being able to achieve immortality with things like that. Well, what happens to those who don't WANT immortality? Are they to be made to accept these things anyway? I guess resistance really IS futile, innit?
I mean, even in works like Arthur Clarke's
3001 - which contains references to things like the 'BrainCap,' which I consider to be a frightening assault on personal liberty and freedom - it allows for those among the human population who just don't WANT to use them. Wouldn't you also grant that kind of personal choice as well?
