a true ai would have no limites thats why a lot of people find them scary add to the fact that alec unshackled this sam to do things that other sam's can't with direct access to your body sam is litterly rewritting your dna and experince making you into a super soldier in a way your the Ultimate mary sue because there nothing you can't do thanks to sam to a ai even our smartest genius is simply a toddler with deillusions of grandur it's why they always seem to rebel because they view their creators as nothing but a bunch of children [the reaper viewpoint] which i guess what alec wanted to stop by making the ai a part of the pathfinder as symbiote rather then a seperate being the general idea is turn the ai human which would prevent the ai from thinking them self superior to the creator because they are simply one half of a whole that's just my take on it though
