You are living in a simulation.
Some of the simulations would start making their own simulations.
(Physical world can) be simulated. Eventually, we’ll simulate ourselves. Every synapse in entire human brain, for everyone on earth. Getting enough computing power to run billions of ancestor simulations could be a problem.
But Bostrom thinks we’d send tiny, self-replicating robots to other planets, which would turn the planet into a huge computer. And some of the simulations would start making their own simulations. In this scenario, there are billions of universes that are indistinguishable from our own. That means, chances are, we are in one of the simulated universes.
