Location of Civilizations Past the Singularity
If other advanced civilizations are similar to ours but much older, we would expect that they already have moved beyond the point of a singularity. So these entities wouldn’t necessarily be located on a noisy planet in the so-called habitable zone, but rather such civilizations might prefer locations with little electronic noise in a dry and cold environment, perhaps in deep space or shielded by space time, where they could use elements of superconductivity for super intelligence and quantum entanglement as a means of communication.
