Coexistence with other Intelligent Species

This is an argument, not about whether they exist now, but about when they exist in the future. The first and foremost alternate intelligent life form to Humans likely to emerge would be Artificially Intelligent non-organic lifeforms. Following that would be genetically mutated or modified animals. With modern Humanity as the template, it seems almost inevitable that more intelligent species would emerge as a result of our presence. Now, different species may easily have different natural thought tendencies, but whether or not that would lead to more bad or good is a very difficult question. Of course, like most things the truth of the matter is likely a gray area. Suppose there is scenario alike 'The Federation', a collective of various intelligent species of different traits who are willing to coexist and collaborate. I think for most people, if they were to go out into the Universe, they would prefer this scenario. If other species have somewhat similar thinking, then it's even more likely for such a thing to exist. In a Federation scenario you have a much wider variety of ways of thinking. Inspiration could be more easily drawn from many sources. With multiple species that have advanced in various ways, it becomes more likely for scientific advancement to come more easily which in the long run is a factor in the survival of any species so it is mutually beneficial. In a Federation there is another benefit, although it is more easily applied to those who are more long-lived. The plurality of life and exposure to the various cultures that result from a multitude of intelligent species is likely to be much greater than what a single intelligent species can achieve on it's own. (At least in a limited time frame) Without such a social construct as the federation, if it were a human mind, the will to live may easily fade over time. If we were to someday develop a greater longevity, the longevity of our hearts and minds would be more easily developed within such a collective. Of course, there are always counter-points to such benefits. Betrayal and distrust can exist in relationships between humans and it can easily exist between different species as well. If a Federation exists then, although unlikely, there may come to be some technology in the future we develop that may easily be coveted. It is not as though technology has to be overwhelmingly advanced to be valuable after all. It need only be unique. Even if a majority of the species in the federation have good intentions, there is always the possibility of a few bad eggs existing. Plus there is also the possibility of forces outside of that federation existing. Mixing with the federation before having sufficient strength could lead to our own annihilation, even if simply through an information leak others would think nothing of. The alternative to joining the Federation would more or less to be Isolationists. Maintaining friendly relations with the federation would likely be entirely possible but whether our technology surges or remains eternally inferior would depend on us. Of course, this could also lead to annihilation if we just sit around with no backing for an extensive period of time. In my opinion, the 2nd option would still lead to groups breaki ng off to try and join the federation eventually anyways. Assuming if the federation already exists, that they would be willing to let them join.
