Nick Bostrom & Ray Kurzweil – Could Our Universe Be a Fake?



A word from the experts…

Robert Lawrence Kuhn, creator and host, “Closer To Truth” via Space.com:

    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.”

    Bostrom is not saying that humanity is living in such a simulation. Rather, his “Simulation Argument” seeks to show that one of three possible scenarios must be true (assuming there are other intelligent civilizations):

        1. All civilizations become extinct before becoming technologically mature;
        2. All technologically mature civilizations lose interest in creating simulations;
        3. Humanity is literally living in a computer simulation.

    His point is that all cosmic civilizations either disappear (e.g., destroy themselves) before becoming technologically capable, or all decide not to generate whole-world simulations (e.g., decide such creations are not ethical, or get bored with them). The operative word is “all” — because if even one civilization anywhere in the cosmos could generate such simulations, then simulated worlds would multiply rapidly and almost certainly humanity would be in one.

    As technology visionary Ray Kurzweil put it, “maybe our whole universe is a science experiment of some junior high school student in another universe.” (Given how things are going, he jokes, she may not get a good grade.)



Robert Lawrence Kuhn, creator and host, “Closer To Truth” via Space.com:
Kurzweil’s worldview is based on the profound implications of what happens over time when computing power grows exponentially. To Kurzweil, a precise simulation is not meaningfully different from real reality. Corroborating the evidence that this universe runs on a computer, he says, is that “physical laws are sets of computational processes” and “information is constantly changing, being manipulated, running on some computational substrate.” And that would mean, he concluded, “the universe is a computer.” Kurzweil said he considers himself to be a “pattern of information.”
“I’m a patternist,” he said. “I think patterns, which means that information is the fundamental reality.”

In the beginning was the code

The universe seems incredibly complex. But could its rules be dead simple? Juergen Schmidhuber’s fascinating story will convince you that this universe and your own life are just by-products of a very simple and fast program computing all logically possible universes.



Juergen Schmidhuber is Director of the Swiss Artificial Intelligence Lab IDSIA (since 1995), Professor of Artificial Intelligence at the University of Lugano, Switzerland (since 2009), and Professor SUPSI (since 2003).

He helped to transform IDSIA into one of the world’s top ten AI labs (the smallest!), according to the ranking of Business Week Magazine. His group pioneered the field of mathematically optimal universal AI and universal problem solvers. The algorithms developed in his lab won seven first prizes in international pattern recognition competitions, as well as several best paper awards.
Since 1990 he has developed a formal theory of fun and curiosity and creativity to build artificial scientists and artists. He also generalized the many-worlds theory of physics to a theory of all constructively computable universes – an algorithmic theory of everything.

He has published nearly 300 peer-reviewed scientific works on topics such as machine learning, artificial recurrent neural networks, fast deep neural nets, adaptive robotics, algorithmic information and complexity theory, digital physics, the formal theory of beauty & humor, and the fine arts.

In 2008 he was elected member of the European Academy of Sciences and Arts.
