The same could be said for humans, just look at Bosnia, Syria, Iraq, Afghanistan, Rwanda. Lot's of examples.
Conflict is part of life, so is cooperation.
Just because conflicts can happen it doesn't mean it's the only thing that can and will happen or that it's the final and ultimate state of things.
Saying that Synthetics can't coexist because they "can" get into a conflict with non-Synthetics is like saying Jews can't coexist with other people because they get into conflict with other people, it seems like a racist sentiment. If you can't expect Organicbeings to never ever ever get into conflicts with eachother, why should Synthetics be held to a different standard?
The Reapers were optimised to be Reaepr controled, the Citadel and the Catalyst however arn't, the Catalyst is trapped on the Citadel, it's home, where it was created, a dwelling it can't control due to design.
Except that this conflict is always devastating. Again:
EDI awakes --> Every soldier on Luna dies (everyone within her power to kill)
Geth awake --> 99% of the Quarians die.
Metacon war --> would've been fought to extinction had the Reapers not intervened. (the extinction of the synthetics, in this case)
The Catalyst want's to save all life, both organic and synthetic.
And stop saying that it's a chance that the conflict will happen; it's not. Every instance we know of in the MEU of AI ended in at least the (near) annihiliation of it's creators or otherwise everything within the reach of the Synthetics.
For the rest, I'm at work. I don't have time for huge post, so ead my earlier post on the previous page about the conflict.
-all organics will create synthetics. This is the nature of organic life.
-conflict will follow, cause organics will try to control their creations, or destroy them (again, this happens in every instance of AI in the game, except the Catalyst itself, who seizes control of his Creators. This is still a conflict though)
-the initial conflict is created vs creators, but by nature it is also always organic vs synthetic. Only one of the participants has to decide that organic = creators or created = synthetics (which is 100% true in every case btw, by nature of the conflict), and the conflict will escalate.
-in the case conflict for whatever reason doesn't occur, it does not solve the problem. In the case lasting peace is achieved, the problem is not solved. See the first point.
There is only one counterexample in the game: the Zha'til (organic race of the Zha combined with symbiotic AI tech). But they were perfect symbionts, only corrupted by Reaper involvement. The Zha reached Synthesis on their own. There was no created vs creator conflict here because the created = creators. This is what synthetis tries to achieve for the entire galaxy.
And this took way too much time
