Also consider the speed of light is also the speed of causality. If there was no such limit it means it would be possible for effects to precede causes which would lead to a very different kind of universe!

What even is the speed of causality? Is there any way to determine that causality has made it halfway from cause to effect?

Or is this just a metaphysical way of saying that no particle can move faster than the speed of light, assuming that causality is just an abstraction of moving particles around?

Network propagation delay ;-)

Imagine the world without a speed of causality, where everything was updated instantaneously. No CAP theorm, no Byzantine generals.

Being a programmer/information theorist would be so much easier lol
