This is about whether something that had it's parts replaced remains the same "thing" - but we were talking about consciousness here, and there would be no copy nor consciousness gap with the described process. Plus, this problem is solved in practice for us humans anyway: all of our cells are regenerated and replaced by new ones every few years, yet we consider ourselves to be the same persons.

Not all of our cells are replaced as you describe. Some cells in the brain, heart, and eyes last throughout our lifetimes. I'm not making any particular claim that our identity as minds hinges on these three types of cells (though such a case for the brain cells seems, prima facie, like a possible good direction), but if you are going to make claims about what our identity as minds does not hinge on, you should take more care to get the facts straight. ref1: http://www.thenakedscientists.com/HTML/content/latest-questions/question/2961/ http://www.thenakedscientists.com/HTML/content/latest-questi... ref2: http://www.usatoday.com/tech/columnist/aprilholladay/2007-03-30-cell-lifetime_N.htm http://www.usatoday.com/tech/columnist/aprilholladay/2007-03...
