...and yet he never bothers to actually articulate whatever point he is trying to make.
Actually, "math" would suggest the universe is teeming with life.
Now, as to the Fermi Paradox, "where is it, why haven't we seen it?" well that's a different issue entirely.
There are plenty of interesting theories on why that should be, even if the universe is filled with life.
My current line of thinking is that highly intelligent/advanced life may not be nearly as common throughout the universe as we might think. Like we might be the most advanced/only advanced civilization in our galaxy, perhaps.
If that's true throughout the universe, it could help explain why we haven't been visited.
The question is what is the broken link in the chain of the Drake Equation.
No one really knows, but it gives rise to interesting discussion.
