Why do we grow from stem cells such fragile bodies, which then anyway have to be replaced again and again, if we can once and for all, create a body of more reliable materials. Stronger, not subject to any aging or to any other impact, the new authorities will be able to give us not only immortality but also — new opportunities. Bones will become stronger, they will no longer break, the muscle is not made of flesh and graphene, for example, allow yourself to raise arbitrarily heavy weight. Eyes will be equipped with night vision and a good zoom lens. It’s a dream, not the body.
