Patrick Wood warns of the Technocractic Transhumanist alliance-- and Google-- this is where Kurzweil is coming from, no doubt. Bill Falloon did not mention in his intro that they "type" of cryonics that matches up with Kurzweil's vision is gluteraldehyde + uploading as envisioned by Seugn and Hayworth. This is far different than the Saul Kent type of 21st C. Cryonics using supercool 2000. I think we're all going to have to delineate the kinds of personal preservation we're all talking about and not conflate them. My own version I've dubbed Quantumonics. I think we're ALREADY backed up into a quantum aether cloud being projected into our biological body and brain in dualist situation. The latest quantum computers might also be able to accept signals from the quantum realm and therefore may become "hosts" for quantum-souls that preexist the AI computer. See Matzke for those references.
