That&#x27;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?<p>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.<p>Replace a knee or a hip with a comparable structure of equivalent practical necessity, and that person will still be missing those body parts.<p>Claims such that, simply because the replacement is infinitesimally complex, that this sufficiently satisfies the requirements of &quot;being a living human&quot; will still be wrong.<p>You might enjoy a puppet that acts just like your dog, or your grandma, but it won&#x27;t bring them back, or keep them alive beyond their expiration date. Put your grandma&#x27;s Moravec replacement brain inside your dog&#x27;s body, and tell me she&#x27;s still alive.<p>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.<p>But still a lifeless corpse all the same.
