I began bemused. The notion that humanity might be living in an artificial reality — a simulated universe — seemed sophomoric, at best science fiction.
But speaking with scientists and philosophers on “Closer to Truth,” I realized that the notion that everything humans see and know is a gigantic computer game of sorts, the creation of supersmart hackers existing somewhere else, is not a joke. Exploring a “whole-world simulation,” I discovered, is a deep probe of reality.
David Brin, sci-fi writer and space scientist, relates the Chinese parable of an emperor dreaming that he was a butterfly dreaming that he was an emperor. In contemporary versions, Brin said, it may be the year 2050 and people are living in a computer simulation of what life was like in the early 21st century — or it may be billions of years from now, and people are in a simulation of what primitive planets and people were once like.
Philosopher Nick Bostrom, director of the Future of Humanity Institute at Oxford University, describes a fake universe as a “richly detailed software simulation of people, including their historical predecessors, by a very technologically advanced civilization.”
It’s like the movie “The Matrix,” Bostrom said, except that “instead of having brains in vats that are fed by sensory inputs from a simulator, the brains themselves would also be part of the simulation. It would be one big computer program simulating everything, including human brains down to neurons and synapses.”
