This document discusses research into developing artificial brains and virtual simulations of human brains. It outlines projects by IBM and the Blue Brain initiative to map the human brain and develop computational models of brain functions. The goal is to upload a human brain into a machine so that a person's intelligence and memories could survive death. This could allow people to remember things without effort and keep skills and knowledge alive. The document compares natural and artificial brains and notes both the potential advantages like immortality and reusing intelligence, as well as disadvantages like dependency on computers and risks of technology being misused.
