But if the universe is a simulation, who is simulating the simulator?

[moffkalast]

The simulator also simulates itself, it's more efficient that way.

[b3lvedere]

The original creator of Arthur C. Clarke.

[AngaraliTurk]

It could be a recursive simulator.

[aswanson]

A kubernetes cluster.

[resource0x]

Simulators all the way down.

[commieneko]

It's simulators all the way _around_. A simulates B which simulates C which simulates A.

Looping recursive simulation... That sounds very interesting and very very scary somehow.

Now i haven't done any recursive programming except on some basic programs on the ZX Spectrum many many years ago, but it felt kinda weirdly evil and forbidden when i was able to order code to modify itself.
