And he saw that it was good

In 1984 Arthur C Clarke, the science fiction author who wrote most notably 2001: Space Odyssey, submitted a pithy short story titled “siseneG” to Analog magazine with a cover letter explaining “This is the only short story I’ve written in ten years or so. I think you’ll agree that they don’t come much shorter.” As you can read above, he’s quite right. Among other broad themes, this story touches on the notion of “Digital Physics,” especially Professor of Philosophy Nick Bostrum’s exploration of the theory that we may all be just living in a giant computer simulation:

He suggests that if it is possible to simulate entire inhabited planets or even entire universes on a computer, and that such simulated people can be fully conscious, then the sheer number of such simulations likely to be produced by any sufficiently advanced civilization…makes it extremely likely that we are in fact currently living in such a simulation.”
