I do not think it is that straight forward.
> But will it be the "same person"? Does cold-starting from the same neural network give you the same consciousness or a copy? Does consciousness require some form of continuity that's lost if you lower neural activity beyond a certain level?
The sense in which consciousness is used in the comment does not have a commonly held definition to my knowledge.
I would be surprised if the poster is using a personal rigorous definition of consciousness in the comment. I have not see a rigorous well defined definition of consciousness when paired with any question along the lines of "But will it be the same person?
I would say it could fall into:
"Please avoid introducing classic flamewar topics unless you have something genuinely new to say about them."

Though it is more of classic for using ill defined words and concepts that people nonetheless hold near and dear.
Though think it is a good police to only down vote a comment like that if the full conversation by the poster continued to use ill defined concepts rather then refining them through out the conversation.
