FTA:
Either extraterrestrial civilizations (ETCs) are incredibly rare (or non-existent), or they are deliberately avoiding contact with us (aka. the “Zoo Hypothesis“).
There is a 3rd possibility - it may not be deliberate.
Our position in the Milky Way is really out on the ass-end of it. We are nowhere near galactic central. If our current understanding of slower than light travel is correct, it just may not be possible for other civilizations to reach us.
When it comes to communications, and our radio sweeps of the galaxy turning up nothing, well, we’re assuming any advanced civilization is still using radio transmissions.
Look at our recent experiment with laser based communication:

100 or so years after radio communication was widespread, we have the technology to eliminate it. There may be other methods orders of magnitude beyond that. We could be awash in alien communication streams we just can’t percieve because ours our too primitive.

All this time? What like less than 100 years looking only? That’s a blip on the cosmic scale. 100 lightyear sphere of our galaxy is what, less than 1%? With all the theories and possibilities of what’s going on out there, it’s way too rash to start theorizing like this in my opinion.
