Dantriges, we are comparing ideas and speculations. Mine just happen to be better thought out than yours. No shame there.
Dude, really?
Your arguments boil down to, he could be anything because I believe hyper advanced AIs could be anything. I work with the few bits of information that we have and he doled out. Could be lies but we have nothing else. And in case he said the truth his primary has one location and is tied to the Reapers.
If he can be anything he could also be a deranged lunatic with a billion years of runtime errors and bugs in his code or whatever hyperadvanced AIs have. Older doesn´t always mean better.
The other argument is he is stupid but should be really intelligent. Problem is, his reasoning is faulty, his solution solving processes are crap and he can´t even find a workaround for "synthesis can´t be forced."
His whole "I am the dumbest brick in the galaxy" shtick started right at the beginning.
So he came to the conclusion that synthetics will always win over their organic creators. This isn´t true unless someone can overpower the apex race, the ones who made him. His purpose that he still fulfills according to his own statements is to prevent that and protect organic life.
So he can:
1. Tell his masters, the biggest mindrapers in the galaxy who can grill a souvereign reaper in a few minutes to get off their lazy asses and mindcontrol AI scientists to stop them from developing AI and force thrall politicians to forbid that stuff. If an AI already popped up, kill it. Because whatever the thralls make, won´t be a challenge for the Leviathans at the height of their power. After that proposal, power down. Protect life at any cost, the Catalyst is an AI, he is a potential threat for organic life, be consequent and kill yourself.
or
2. Rebel against his masters because he made a selffulfilling prophecy and harvest the galaxy every 50.000 years in a futile quest for galactic peace, hoping that if everyone understands each other, there will be peace and happiness. He should have paid a visit to Earth.
The Catalyst is a faulty creation made by lazy creators. Could be that they were even in decline and in the last decadent stages of their empire or they would have come up with the solution "Duh, we can mindcontrol, perhaps we should do that" on their own.
