Digital Heaven

§1. If you had the opportunity to live forever, would you take it? The obstacles to keeping your body alive indefinitely still seem insurmountable, but some scientists think there is another possibility opened up by digital technology: creating a digital copy of your "self" and keeping that "alive" online long after your physical body has ceased to function.

§2. In effect, the proposal is to clone a person electronically. Unlike the familiar physical clones - offspring that have identical features as their parents, but that are completely separate organisms with a separate conscious life - your electronic clone would believe itself to be you. How might this be possible? The first step would be to map the brain.

§3. How? One plan relies on the development of nanotechnology. Ray Kurzweil - one of the prophets of artificial intelligence - predicts that within two or three decades we will have nanotransmitters that can be injected into the bloodstream. In the capillaries of the brain they would line up alongside the neurons and detect the details of the cerebral electronic activity. They would be able to transmit that information to a receiver inside a special helmet or cap, so there would be no need for any wires protruding from the scalp.
