Would You Become An Immortal Machine?

Marcelo Gleiser: The idea is, in principle, simple. As you die, your body is caught fresh and rushed to a coffin-like cylinder filled with liquid nitrogen, where it will be frozen, either in full or just the head, until such time when either the cure for your ailment is available, or the technology for a full brain upload is ready. In both cases, the goal is to give you the possibility to live forever, even if this thing that lives forever is not really you. Or is it? What defines you, anyway? Such is the premise of Mark O’Connell’s outstanding book on transhumanism, To Be a Machine: Adventures Among Cyborgs, Utopians, Hackers, and the Futurists Solving the Modest Problem of Death.
