That's all just boiling frogs. Why should we consider the a structure that subsumes the space of an organic human brain to be a living continuation of the original brain? The deconstructionist concepts that our constituent atoms cycle through a complete change-over in less than a decade, does not equal total organ replacement with a non-biological surrogate. Those sorts of ideas sweep a grand swath of what-it-is-to-be-alive under the carpet with a sentence-long sound bite. Replace a knee or a hip with a comparable structure of equivalent practical necessity, and that person will still be missing those body parts. Claims such that, simply because the replacement is infinitesimally complex, that this sufficiently satisfies the requirements of "being a living human" will still be wrong. You might enjoy a puppet that acts just like your dog, or your grandma, but it won't bring them back, or keep them alive beyond their expiration date. Put your grandma's Moravec replacement brain inside your dog's body, and tell me she's still alive. A human without a human brain is not a human, but instead a soothing, reassuring puppet, perhaps hoisted aloft by hypothetical autonomous, and nigh-imperceptible nano-cyber-strings. But still a lifeless corpse all the same.
