The Great Filter hypothesis assumes that a society that has the capability to expand and colonize would do so without exception and make its presence known to more primitive civilizations. That's a pretty big assumption. Just look at how ridiculous most futurism of the early 20th century already seems (both culturally and technologically), and then consider trying to relate to the continuation of human civilization after ten million years. When we try to envision the future, it is still rooted in the familiar. I suspect ten million years from now (if our society continues on that long in some capacity), just about everything will be so fundamentally unrecognizable (including the continuation of humans, if there is still a biological form at all) as to make relating to their intentions or even trying to identify whether they exist from afar with primitive technology futile. There's more hard evidence of "pseudo-magical objects that don't seem to wish to be seen up close" here on our Earthly radar systems than there is of the actual conditions on planets in neighboring habitable zones to confirm or deny life and start establishing probabilities.
