I don't believe that a copy of someone's consciousness, even if a perfect copy, would ever "be" that person. That is, unless you could perform some kind of live-transfer where the live person's sentient persona could intentionally traverse the gap between their original body into the new destination. Otherwise, the original person is just dead and you made a copy.
Edit: The same thing goes for teleportation. If they disassemble the molecules and reassemble the person at the destination, that's probably a copy and the original person died.
I sometimes wonder about that with doing a sort of Ship of Theseus thing with the human brain. By that I mean, say you could just replace the part of the brain that does something minor like processes taste or controls balance with a chip, you'd presumably still be the same person at the core, just with a chip doing some parts for you. But then if you kept going, at what point would it stop being the original person? Are we the sort of lizard-core part of the brain? What if you replaced that but kept the original part that governs intellect? Are we our intellect? Or some combination of the two? Which parts would end the 'original' person's existence if removed? Could we even tell?
My personal best guess based on philosophy, spirituality, and recent scientific discoveries is that consciousness occurs in some kind of quantum field that is connected to the human brain using quantum effects inside microtubules in neurons. (See this article for some info https://pmc.ncbi.nlm.nih.gov/articles/PMC8393322/ )
There may even be a quantum collective consciousness (like Jung's collective unconscious) that our brains have a quantum link integration with.
So it might just depend on whether or not your personal quantum consciousness field could interface with the new stuff or not.
It's just nice knowing that there are some like-minded people thinking about the same things going on here. Some years ago that kind of connection seemed impossible to me. It's about an ever-developing consciousness and maybe some day it will lead to fundamental breakthroughs. The more we learn, the more we make sense of it for having harmony and a great life in general. Maybe our brains are just projections of everything going on in this universe, let it be micro- and macro- cosmos.
I think sometimes in an implant that gives support to the brain and replicates the neurons as a backup. When a neuron dies the implant gives the brain the equivalent synthetic neuron.
Them MAYBE the person would live on. Otherwise, the original dies and the CPU goes on.
