Elon Musk said we "are very likely living in a simulation."

Suddenly thought of a very interesting support logic:

If the universe is simulated, then there must be an upper limit to the speed of information transmission.
You cannot refresh data faster than the system.

In our world, the speed of light is precisely the maximum speed for all information.
Nothing can surpass it.

This sounds very much like a characteristic of a simulation system:
- The processor has a maximum frequency
- The network has a bandwidth limit.
- The game world has a tick rate
- The simulated universe may have a "maximum data transmission speed"

Perhaps the speed of light = the refresh rate of the universe's underlying engine.
It's not proof, but it is indeed an interesting perspective.
