Imagine a sci-fi world where many organic civilizations would have raised and have an empire between many planets and systems. Even if there is some political tensions, they all live in peace together. (A Mass Effect-like universe).
Now, for some reason, imagine a race of machines, with a population of individual artificial intelligences, that found its own empire - or republic, whatever.
Let's suppose that they didn't harvest or even declared any war to their creators. For instance, their creators could have released them when they felt to start an undefined behavior from them, and let them found their own society on another system rather than risk a war.
At this point, may them prosper alongside other organic civilization ? They would have a strong military power, but wouldn't use it on anything unless they feel directly attacked. So in theory, peace would be possible, but:
- A machine group could repair they old members while creating new ones, so its population (and so space needed) would grow up faster than any race. Colonization of new world would be quickly a problem with neighbors.
- They needs for food or atmosphere quality are null, and their energy resources needs are higher than organic (as they need energy for themselves before anything else to 'live') so if they colonize a habitable world, they could find useless to let any animal or vegetable life form on it and destroy anything for industry profit. Other intelligent organic species wouldn't like that.
- Diplomacy and political games are probably hard to understand for a machine, so if they try to have a role in galactic governments (as ambassadors for instance) this could leads to more political incidents than anything else, disturbing a fragile peace.
So is there a chance at all to develop at peace with other races ? If yes, at which conditions ? If no, why specifically ?
