Special relativity and the speed of light impose some fundamental lower bounds on the cost of consistency: https://en.wikipedia.org/wiki/Relativity_of_simultaneity https://en.wikipedia.org/wiki/Relativity_of_simultaneity . This theoretically manifests as lower bounds on the performance of consistency in distributed systems.
