This will end so bad... People shouldn't mess with mother nature... I was making project work in school about predictions about world end and this kinda creepy stuff, and one of the seer was saying people will invent this. And after sometime it will give people a lot of tragedy, for example people will feel awful and they couldnt die in normal way, only if they committing suicide... People will live up to 450 years. Imagine how hard is when u are already 100 years old... well in your 400 you wont be able to move or even use pc... This is horrible!
So, we are going to be able to "live" forever as humanoid robots? How boring, the best part of being human is that we are able to feel, to touch, to fall in love, and to think about living forever without any of those things is just I will not be against human nature, thank you very much.
