It’s all pure speculation what the alien races coming here might be like, in their mental makeup, since we only have ourselves as examples of intelligent behavior, and not very comforting examples, at that, being the violent, selfish creatures that we are.
It’s a pretty safe bet that they’re all ancient races in our terms, meaning they began developing advanced technology eons before we did. Another safe bet is that each race is unified politically, or governmentally, however you want to look at it.
I would think that at least one of these alien races has developed telepathy and if not, has developed technology that allows them to speak to each other mentally. This would be huge in traveling among the stars as telepathic communication is instant regardless of distance.
Or not, since some Australian scientists succeeded years ago in “teleporting” a data carrying beam of light from one place to another with zero time loss. If we can do it now, surely they can do it a lot better.
So with all this technology, very likely advanced to the point of final conclusion, what are they like as people?
Highly conformed, would be my guess. Very little individuality, if any. Not much sense of self, like really brilliant ants. That means they would have little to no regard for us as beings. We would be objects of study, experimentation, of scientific interest ala National Geographic Magazine. Or maybe not because…
Logically, any space-faring race wants to colonize other planets, and these races probably have all spread themselves out across our galaxy and are still doing so. Give it enough time and differences will develop between the various colonies, even though they stay in contact with each other.
I doubt that they have soul-less personalities because of the obvious fact that they could have gotten rid of us and taken over Earth thousands of years ago, but they haven’t. We may have very little actual value to them as a species but they aren’t here in such great numbers without reason, which leads me to think that we’re being cultivated for a purpose.
It could be that they’re lonely, simple as that. There may not be but a few intelligent humanoid races within a hundred light years or so, and leading us into a level of technological and social advancement sufficient to join them on a sort of apprentice level may be the goal here.
Meaning that they intend humanity to join their ranks on their terms and in their time. And if that’s true, then they’re people with goals and purpose and not just curious, jaded and ancient and uncaring.
If that’s the case, then they’re less concerned with who and what we are now and more focused on what they intend for us to become, which could well be a few thousand years in our future yet.
Meanwhile, we can hope that they’ll protect us from each other and keep us from wiping ourselves out with manufactured plagues and nuclear weapons until we reach some basic level of parity with them.
