How close are we to visiting other worlds? Not very. We're an adolescent race that is still finding an identity and hasn't passed Driver's Ed yet. And when we do start, it will be via slow methods of transportation, so we won't be able to reach out very far.
If by chance, another intelligence in our same state of development were to find us, I think we'd be pretty similar. Struggling to outgrow our biological biases (all of which I expect are fairly universal to any biological life form). Struggling to "express ourselves" which is what creates all of the diversity that in turn creates all the tumult in our societies. They wouldn't look at us and think "boy, what a bunch of losers", they'd just see another example of themselves.
On Star Trek, Alien races tend to be presented as not having much diversity. Sure, some Klingons may have ridges and others don't, but they all generally agree, Kahless is awesome and so is bullying people. And so on.
Perhaps this is because these intelligences capable of faster, further space travel have gone on from adolescence to adulthood, and know who they are, and are comfortable with it, or have more pressing concerns (or lofty) than "expressing themselves". (More likely it is bad writing, but hey, maybe reality would turn out to line up with that bad writing...)
So perhaps we will get there too.
And in that case, what interest does an adult have with a teenager, except to ignore them or assert their own "wisdom" over them?
Just some thoughts.
