SETI PRESUMES that the way we're going to detect extraterrestrial civilizations, is their beaming TONS of photons at us, in crisp signal.
WHY TF would they do that??
Why wouldn't they ditch the energy-wasteful TV-style broadcast, for energy-efficient fiber-optics?
There's, in my view, only a SINGLE century of civilization-evolution in-which tons of broadcast energy is poured helter-skelter all throughout the sky.
Before that it isn't done because the tech doesn't exist, & after that, it isn't done because it's idiotic to be doing it.
So, instead of presuming "all civilizations are broadcasting, why aren't we seeing them??", we OUGHT be presuming "we're trying to see a single-century of civilized-evolution, & maybe this is the wrong method for finding other-world's life".
