Fermi Paradox vs. Copernican Principle?

[Stuart LaForge]

My question is kind of simple, but it really belies a pretty strong
philosophical tension that seems strangely unaddressed. The Copernican
principle is a cornerstone of the science that says that we are in no
way special and instead represent an average and unremarkable place
within the universe. The Fermi paradox, on the other hand, seems to
strongly imply that we are the only life form in the galaxy that is both
intelligent enough to understand physics and dexterous enough to build
technology capable of leaving the planet and sending signals to other
stars. Obviously, if we are the only technologically sophisticated
lifeforms in the galaxy, or perhaps even the universe, then that means
that the Copernican principle is patently false, and humanity holds a
privileged position as the first technological sapient species to evolve
in our light cone, or the subject of a cosmic simulation or experiment
focused on us i.e. God's ant-farm.

I would love to hear everyone's thoughts on the matter.

The Copernican principle is very far from being a cornerstone of science and is in fact patently false. The average cubic meter of space in the observable universe is almost a perfect vacuum, it only contains one hydrogen atom; if you look around you will see that we must be living in a VERY unusual place.

Yes.

If there were a civilization that was type 3 on the Kardashev scale anywhere in the universe then we would've spotted it many decades ago, but we see nothing. If intelligent life is common in the observable universe then at least one individual is going to use Nanotechnology to make a Von Neumann Probe, and that would lead to a type 3 civilization, so I disagree with Carl Sagan, sometimes the absence of evidence is evidence of absence.

Exactly. And that really shouldn't be difficult to believe because the observable universe is huge but finite, so somebody has to be the first.
