More thoughts on the phrase:
Catalyst: “the creation will eventually rebel against its creator”
In my view, that is the synthetic attempting to preserve itself. Instead of stamping out the rebellion (synthetics) Catalyst is dancing around the issue that if organics were allowed to evolve, then those organics could dismiss them with a thought – so keep them primitive. Alternatively if synthetics could self-evolve (not network-evolve), then synthetics could dismiss organics with a thought.
If the phrase was true, then the Geth would rebel ONLY against Quarians – and they don’t. The “heretic” Geth set traps & kill humans, turians, asari, and other organics that are NOT their creators.
The statement is flooded with superfluous & non sequitur words. In reality:
Any sentient being will oppose an oppressive rule. It [obviously] doesn't matter if either end is synthetic or organic.
It doesn’t matter who the created are -- or who the creator is. The words “the creation” and “its creator” can be thrown in but doesn't add anything to the situation.
In the reapers case, they didn't create ANYTHING so Catalyst’s statement is nonsense. Self preservation.
Oh,yes -- they created the mass relays & Citadel -- which haven't rebelled (yet).
Think about it:
If the statement is true
-and-
Catalyst created the reapers
-and-
MIL-yuns & MIL-yuns of years have passed
-then-
Your upper left brain logic circuits would conclude that --
Catalyst & reapers would be at war with each other.
