Imagine we learn to read human brains down to the most intricate details. Imagine we learn to record, in detail, every action that occurs within the brain, every synapse firing, every cell interaction, every memory. Imagine if all of this data could then be stored on a computer and used to re-engineer a new, identical brain. Imagine this brain could then be put into a new body, thus creating a new version of us when we die. Imagine we knew for a fact that there was nothing after death. Imagine we live forever using this, or some other mind transfer technique. Imagine then we discover another civilisation on another planet, who is still too primitive to save minds, and who still believes that death is natural and essential. Imagine we then engineer a situation, for example we send swarms of microscopic probes to their planet to monitor, transmit via microscopic satellites, and then record their minds on our computers. Imagine we use this data to re-engineer the brains of these p
