Hypothetically, if an alien civilization powered itself through a mesh of evenly-distributed orbiting solar power stations (a Dyson sphere with one-billionth coverage would still produce in an insane amount of power), would we have any way of noticing?
My hunch on the Fermi paradox is that the space-faring phase of a civilization requires transitioning into immortal software, dodging around the speed limit of c by becoming very old, and very patient. I suspect such life forms ("Space Ents") wouldn't bother trying to communicate with such rapidly churning species as ourselves, other than perhaps collecting data via probes to be perused hundreds of millennia later.

We know for a fact that such a satellite would have a good chance of spotting any star farers that are remotely like us, even if they are significantly more advanced but still "fast" in terms of their energy use and general way of doing things. Space Ents belong to a long tail of other possibilities, but they also must obey the second law...
