Fell to the ground and doesn't move? Don't hear breathing? No heartbeat? All those have been "brought back to life" myriad times, so the legal/societal definition of "death" keeps getting its bar moved up. When scientists finally determine for certain as to where and how memories are stored, and what constitutes identity, I would not be surprised to see cryonic preservation of whatever those things are, become the standard medical practice. In other words, you would be malpracticing and breaking the law if you did not cryopreserve someone who met the criteria for not yet reaching information theoretic death. Not only that, future societies would be going against their mores and laws to not reanimate someone who could be with their current technologies. I don't see the future as bleak as Basie does.
