Elon Musk is pretty sure that we’re in some sort of simulation.

At Code Conference this week, Musk opined that there’s just a one in a billion chance that we’re living in “base reality,” or the realest of realities.

Musk explained that, given the advances we’ve made in computer graphics and virtual reality in just a few decades, it’s almost definite that there’s a more advanced civilization playing or monitoring us like characters, in a game world that is “indistinguishable from reality.”

I guess I’m fine with being part of a video game, but could they spec me for some cooler abilities next time?

Either way, Musk’s explanation is fascinating, and Vox agrees that his argument is fairly tight.
