Alcor's latest email newsletter looks good in terms of promo but fails to deal with nano vs. quantum scale problems I've introduced here in this forum. They appear to have left serious philosophy of physics such as the hard problem of consciousness behind in favor of a hard marketing pitch. It's not surprising to me however because after all, cryonics ASSUMES that personality and memory are embedded in preservable brain structure. There is no room in the Alcor Newsletter to question that assumption.
