I was making the point that if the assumptions being made were commonplace (life->complex life->intelligent life->space exploration->FTL travel) then we'd see it everywhere because it's had ~15 billion years to develop. The Milky Way alone would have many thousands if not millions of intelligent species. That we have seen absolutely no evidence of this indicates that intelligent, technologically advanced, spacefaring life is either quite rare or not contemporaneous.


Hell, life in general could exist on a few million planets in the milky way while we have yet to look at or detect any one of them. Who is to say how common place it is for intelligent life to develop FTL (making the rather larger assumption that such a thing is possible)?

I agree that your question would apply if the claim was that life which can travel faster than light is common place and that such travel is so much faster than the speed of light that they could travel to any point in the universe (or galaxy if we confine things to the Milky Way) in a short period of time at relatively low cost/expenditure. But even in such a case, would the FTL races have time or desire to visit everyone? What if there are billions of different planets in the universe with life? Would they get to them all? How many races have FTL ability? 1/100th? 1/1000th? Fewer? And this is all assuming such technology does exist.
Oh, but to hear some tell it, any civilization that gets near our level of development will inevitably reach the Singularity, which promises technologies we can't even imagine. At a minimum, there should be Von Neumann probes everywhere, since those are so easy and cheap to build.

Or they have other concerns...if they aren't lonely, if they don't need our resoruces, what are they doing? In a multi-species race for nearly unlimited resources of a black hole at galactic center? Exploring time/multiverses? Exploring endless permutations of a superintelligent AI lifespan?

Sadly, there is no evidence. On the other hand, as exponentially advancing as our technology is, we may also be sadly inadequate to the task of knowing for, oh at least a few decades if not longer..
