&gt; expect we will eventually find that human intelligence and consciousness depends heavily on quantum effects. Thus it will always be impossible to scan and upload a human brain in a way that captures the essence of a person&#x27;s mind<p>And you have a strong reason to believe that emulating or implementing those quantum effects in a structure other than the human brain is impossible?<p>As a secondary argument - if an reacts to all stimuli and behaves in all ways exactly as the corresponding human would, claiming that it &quot;lacks the essence of a person&#x27;s mind&quot; prompts a pretty obvious (and well-considered) question.. how do I know you&#x27;re not just an essence-less entity that acts exactly like a Real Human would act?<p>Or are you claiming that correct emulation of a human&#x27;s behavior is impossible, because &#x27;quantum&#x27;?
