The essence of Rich’s theory is that a “programmer” from the future designed our reality to simulate the course of what the programmer considers to be ancient history—for whatever reason, maybe because he’s bored.
According to Moore’s Law, which states that computing power doubles roughly every two years, all of this will be theoretically possible in the future. Sooner or later, we’ll get to a place where simulating a few billion people—and making them believe they are sentient beings with the ability to control their own destinies—will be as easy as sending a stranger a picture of your genitals on your phone.
This hypothesis—versions of which have been kicked around for centuries—is becoming the trippy notion of the moment for philosophers, with people like Nick Bostrom, the director of Oxford University’s Future of Humanity Institute, seriously considering the premise.
A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre, however subsequent calculations found that such a device would require prohibitive amounts of energy.
Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially bringing the idea back from the realm of science fiction into science.
