I'm not insulting him I'm ripping on his opinion because it is just that stupid. And simply quoting Catalyst without making any point does more harm to the proper discussion than my choice of language. I didn't want to bring this up but honestly that whole line of reasoning boils down to one infamous meme with which, I'm sure, everyone on this site is familiar.
He brought in the core points why the Catalyst is not mad, but instead it does what it's supposed to do. It's not a stupid opinion, it's actually in line with what we know from the game, but it seems some people ignore to see this because they hate on the Catalyst way too much instead of blaming Leviathans for its creation in the first place. Which I do, too, but that is not the Catalyst's fault that it has to work with this mandate they gave it.
I don't remember what Leviathans say exactly, but I'm pretty sure that when they created Catalyst to preserve organic life they didn't exactly have greater good of the organics in mind. More likely than not they just weren't too happy about discomfort caused by lack of servants which was in turn caused by synthetics revolts. So ultimately Catalyst's so called mandate was to ensure Leviathans lived happily ever after... The objective which he failed on an epic scale. And let's say that Leviathans did, indeed have greater good for organic life in mind, do you think they meant primitive life forms that barely leave a footprint in the mud or the civilizations that actually leave their mark of their existence in this universe by achieving great feats, creating new things and having thoughts that are more complex than "Ugh I hope that gazelle over there can't run faster than me"? In which case the catalyst in its infinite wisdom failed to comprehend the essence of "life". In either case, Catalyst is a flawed program.
Leviathans said that tribute doesn't come from dead races, which likely means all of them, no matter how advanced or primitive. Yes, Leviathans used them as thralls and were still dominant over them, so of course the loss of organics that could've benefit them was the reason they created the AI in the first place. Leviathans are arrogant and surely did not see how they themselves were a part of the problem as well, I could imagine they even saw themselves as masters of the AI, that it would be obedient and just deal with the "lesser organics" that constantly created new synthetics.
Which they miscalculated clearly and paid for it, but oh well, that can happen when you're full of yourself.
For what the Catalyst is, it does its job. If you don't like the way it does it, that's fine, I don't like it either, but we still can see it's fulfilling its purpose.
Legion also states not to apply human/organic logic to machines and vice-versa. So Geth can't possibly comprehend what they approve of, due to lack of understanding the effect of Reaper's actions have. In ME3 Legion also says that key to being "truely alive" being an individual, having free will, and having morals. The attributes that Reapers and all synthetics lack according to your own arguments. Basically by harvesting races to save them and turning them into reapers Catalyst kills the very life it so desperately claims to preserve. And by the way just because they don't have the concept of morality doesn't negate the fact that what they're doing is absolutely, objectively horrible.
Also as a sidenote I wasn't the one who brought in the morality into discussion. Just because I used the word murder doesn't mean I was on my knees screaming "Oh the humanity". The original Point of this discussion is to point out how ridiculous and childish the Catalyst's solution is.
Your first sentence backs up what I'm saying, organic logic cannot apply to machine logic, and vice-versa. They just don't understand each other and how they view the harvest process is completely different.
And the geth do approve in so far as they're trying to build their own "Reaper", the Dyson Sphere, so they can be united, that's the goal they pursue.
I'm not bringing in morality. I brought in the fact that synthetics think about that solution differently. It's made clear from the dialogue that they consider the harvest, and storing the knowledge and essence of each race inside a Reaper as something good, something positive. In this way organics and what they are/were are preserved for eternity, which means... they're not lost to the conflict, which is what the Catalyst was tasked to do. To the Catalyst and the Reapers this is a good thing and they see it as helping us, which from our point of view is completely ridiculous, but that's how they work and think.
And now to the more obvious reasons why Catalysts whole charade about "most efficient way of saving the organic life" is wildly asinine. BECAUSE IT'S TOTALLY NOT THE MOST EFFICIENT WAY TO SAVE ORGANIC LIFE. There are literally dozens of ways that are easier, more convinient, more efficient, less timeconsuming and less downright retarded, than waging centuries long galactic war every fifty thousand years; which I'd like to point out Catalyist wages by using as Reapers soldiers. Reaprers, that are supposed to be (by his own words) time capsules holding the legacy and culture of races Catalyst supposedly saved by turning them into giant unthinking uncaring machines. That is just baby-town frolics.
Well the problem here is that we don't know what the Catalyst exactly tried out before it considered the harvest as the best temporary solution until Synthesis is actually possible.
We just have to assume that it tried lots of things, maybe also some you think about, and that they just didn't work out efficiently enough.
