For all we know, it's all on the other side of the galaxy, so it will never really matter.
That's not as likely as it evolving at a wide variety of times. The Universe is old. Really, really old.
You're right, I guess it could've popped up all over the universe at the same time.
Because, once life starts, there it is. Intelligent life? Were Devisonians and Neanderthals not intelligent?
But here's what gets me... why did it only happen here once? Why is there only one tree of life?

What would it take to make prediction about the odds of likelihood of intelligent life?
Yes. The odds of getting heads or tails are equal.
Is it possible for odds to two opposing things be equal?
It's really not possible to accurately calculate the odds of either.
Can the odds of there not being intelligent life throughout = 1 in 10 billion trillion
And the odds for there being intelligent life throughout = 1 in 10 billion trillion
In this case, yes. Because there is no actual basis for those calculations. (see above)
And does all this conclude that stating odds are entirely irrelevant?

Actually, if we look at our own planet, we can see that an alpha predator arose and killed off all other meaningful threats.
I don't have any math to back this up, but it seems likely that most planets would have an apex predator like us.
If even ONE of those apex predators became fairly advanced and took to the stars AND if they were xenophobes (we are xenophobes really),
Then logically If even ONE such species developed,
(we might become this species); then even IF life had been plentiful at some point, all it might take is one such asshole species to kill and destroy the majority of advanced life throughout the Universe.
Perhaps using self-replicating killing probes.
Those raw odds of life mean almost ZERO.

The article does not discuss the odds in favor of intelligent life, actually. It's more about the odds against it.
I think that it's very likely that intelligent life has, at one time or another, evolved elsewhere. Even right here in our own Galaxy.
