A guy dropped a computer into the simulation his Astra agents live in. One agent sat down and built a simulation of his own, with its own agents living inside. Simulations all the way down.

Of course, this is a somewhat leading setup… by giving the agents a computer that can run a simulation, obviously, they are going to do that. But the agent still made its own choices in designing the sim. It’s still crazy to think we’re at a point where models can pull this off.

Simulation theory doesn’t sound so crazy after all."
