brain dead does not necessarily refer to damaged brain cells. It often refers to electrical activity. As people have been resuscitated after the cessation of brain activity (i.e. human's are cold bootable) without loss of personality it seems reasonable to still give cryonics a go.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
