It is critically important, especially for the engineers, information technology, and computer scientists who are reading this to understand that the brain is not a computer, but rather, it is a massive, 3-dimensional hard-wired circuit.

The critique reduces to a claim that personal identity is stored non-redundantly at the level of protein post-translational modifications. If there was actually good evidence that this is how memory/personality is stored, I expect it would be better known. Plus if this is the case how has LTP been shown to be sustained following vitrification and re-warming? I await kalla724's full critique.
Thank you for gathering these. Sadly, much of this reinforces my fears.
Ken Hayworth is not convinced - that's his entire motivation for the brain preservation prize.
...“Do current cryonic suspension techniques preserve the precise wiring of the brain’s neurons?” The prevailing assumption among my colleagues is that current techniques do not. It is for this reason my colleagues reject cryonics as a legitimate medical practice. Their assumption is based mostly upon media hearsay from a few vocal cryobiologists with an axe to grind against cryonics. To try to
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
