> Thats a very strong claim which you provide no basis for, in that comment or in your follow-ups. Maybe replication at the level of neurons, as opposed to atoms, would work? Or maybe at an even higher level? We don't know yet. Actually, worded correctly, it's a reasonable claim (assuming pure materialism). If there is nothing but matter and energy and their interaction, then a perfect simulation of all of your cells would undeniably be a perfect simulation of you. The strong and unsubstantiated claim for which no basis is provided is that simply replacing the neurons in your brain would be "enough." There are good reasons to believe that the neurons in your skull are not sufficient (are you still you absent sensory input?) and apart from a lot of philosophical navel-gazing there's no proof forthcoming. Even pure materialism is an assumption--a good and reasonable one when it comes to doing science, but not something I'm willing to gamble my consciousness on.
