Coexistence with other Intelligent Species

I have to say, that you did mention trying the escape the pull of the black holes we revolve around, however that will be quite unnecessary as getting close would take hundred thousands of years, and getting a stable orbit around something is not really that difficult once we become something considered 'space-faring'. Now, onto my actual arguments. 1. Singular species-wide overlord. While this may be a possibility, I find them coming to existence very hard to believe. Who would ever agree to that? Let's look at Europe for this example. The nations there are almost a constant at this point. Europe becoming a singular nation is mostly impossible at this point due to cultures and things of the sort, not to mention the global powers' constant meddling. Maybe these things change when we have more land to conquer, but I highly doubt it. Even if an overlord, so-to-say came into existence as you said, the species will become highly divided. And this is not an opinion. Unless we are always being forcefully "intermingled" with our brethren from other planets, then we'll eventually lose our ability to procreate children with them, simply due to the fact that we're too different. This is a real possibility, though it won't happen for a long time. A singular leader is unlikely, even a council isn't a possibility for humanity. A large parliament without a singular leader, voting on everything is almost the only possibility. 2. Resources. You may think that resources won't be important since we could technically just harvest our sun's energy and then with a currently unknown technology, force atoms into existence in specified patterns. Or simply because we can just find new planets with resources right? Wrong. Unless it is in our solar system, we're very unlikely to be able to harvest. We're in a quite packed part of the galaxy, and even here it is more than 2 light years to the nearest solar system. Communication with radio signals (won't ever change, as this is a very broad term) would need very specialized equipment to be able to focus that much, not to mention the 2 year delay. Communication is key to everything. In not-so recent times, instant long-distance communication did not exist and so, politics was quite difficult. However now, we even have a direct instantanious link between Washington and Moscow, as if it were nothing. To prevent misunderstandings, war, simply whatever we need to be able to communicate with our colonies. However that is simply impossible at that distance. Now comes some fast ones! 3. FTL is most likely impossible. This is quite simple point. Most designs nowadays do technically carry us FTL (though none of them have been tested due to the immense energy needed), however to the outside world you still move slower than light, you just feel like it is faster as time is relative. 4. The Fermi Paradox. Basically, we'll probably die before we become space-faring as did *probably* many others before us. 5. Heat death. Death will always welcome our species with open hands, we cannot escape it, why try? 6. Survival of the fittest. We may be smart compared to other animals socially, but maybe being our definition of social is idiotic and misguided. Maybe we are not the fittest, more like live stock? 7. Science. Like hell they'll give it us for free (unless they're the previously mentioned 'spiritually enlightened' type, if those exist), and what can we give in exchange for knowledge? Energy? No. Maybe becoming a vassal would satisfy them to give it to us, but even that is pushing it. 8. A new frontier. We don't know anything about the outside world, maybe someone is watching this very text, or maybe they simply don't exist. Maybe a god does exist and he created only us, maybe we are just ancestors to a species that tried resetting itself as it thought they failed. The problem is, there is too many ifs that we'll probably never find out. (See, lack of ability to communicate)
