I don't think the comment reflected a degree of sapience. In fact, I think the Catalyst was responding to what it interpreted as a rather racist statement by Shepard, who defined it by a broad category instead of as an entity deserving of consideration. I think it responded in kind, and you've just misinterpreted the statement.
Frankly, your arguments are not compelling. The answers to your assertions are fairly obvious, and have been given to you before on many occasions. Claiming ignorance now by restating them is simply a waste of everyone's time. "Its assumptions are flawed" (a declaration based on, what, one state of peace only achieved because the Reapers attacked? Hardly conclusive), "argues from authority rather than facts" (it has been studying the conflict for over a billion years, does it not have authority, along with a vast history of conflict between Organics and Synthetics as facts?), continues the attack even as it admits that it will not work" (a statement of eventual failure that is not a contradiction of its ongoing action to prevent the total destruction of Organics now, and not an argument to stop the current Reaper cycle).
The ability to change and adapt is the hallmark of life (because even bacteria does that). Self-awareness is the hallmark of intelligent life. The hallmark of intelligence is the ability to reason, and the Catalyst seems to reason just fine.
And how do you know it has not changed and adapted given that the Reaper solution was a change from its previous attempt at a solution? At this point, I feel you are as guilty of the "flawed assumptions" that you accuse the Catalyst of having.
