....The key points of the technological singularity are that, once created, AI will outpace humans (organics) in intelligence, strength, civilization, and wipe us all out. AI lacks empathy. Scientists have long postulated that the reason human's have morality at all is empathy. We can imagine ourselves in someone else's shoes and thus invision what it would be like. Therefore we can figure out what we don't want to happen. In fact, empathy is so important that a lack of it is considered a mental disorder (it makes one a Psycopath). Since AI doesn't care about us by some intrinsic order of its being, it will view us as just more parts of the universe, like rocks. It could wipe us out as a means to prevent natural disasters, or harvest us as resources. It could even take its main task, such as building widgets, too far and wipe us out in an attempt to optimize its goal. Those are key points that need to be explored for the technological singularity to make sense.
So let me state up front, it is not a lack of knowledge of the technological singularity that has people pissed. Do you really want to argue that the set of people playing Mass Effect and the set of people who have seen "The Matrix" are really disjoint? Come on here. There is a ton of popular references to the technological singularity in all forms of narrative. Movies like "The Matrix", "I, Robot", "The Terminator", stories like "The Evitable Conflict", "The Last Question" by Asimov, "I Have No Mouth, and I Must Scream". And those are what I can come up with off the top of my head. People playing Mass Effect are plenty familiar with the concept of the Technological Singularity, even if they cannot tell you the name of the concept. The problem is that they were not told to care about the concept in the entire story arc of Mass Effect (even including the end). Let's start with this, there are 3 Artificial Intelligences explored in the main story Mass Effect. The Geth, EDI, and the Reapers.
The Geth start out as villains that could easily have explored the Technological Singularity. In Mass Effect 1, they are villains working for Sovereign to kill organics. Their motives are mostly unknown, and could have easily degenerated into an exploration of the Technological Singularity. However, that exploration all falls apart with one word: Legion. The Geth are not a uniform species of AI's bent on harvesting us (though the reapers are!). They are a civilization. They have internal conflicts, Geth vs. Heretic Geth. They have goals like becoming strong with their own two hands, not by taking the Reapers tech. They compromise said goals. The Geth are an exploration of the awakening of consciousness. Consciousness is considered one of the great unlikely events in Human evolution, and the Geth are a direct exploration of how that could happen. The problem is, nowhere in any of the full Geth story line do any of the main points of the Technological Singularity get explored. Where is the indifference to organics? Sure, they are isolationist, but they aren't indifferent. Even without the morning war exploration in Mass Effect 3, the Geth are not a representation of the Technological Singularity, they are directly referenced as a species that happens to be synthetic, not a representation of a species defined by the fact it is synthetic. By the end of Mass Effect 3, they Geth are fully actuallized real people who make decisions based on information, survival, and empathy. Even more so if they survive, they become full individuals. The presentation of the Geth is one of a civilization comming in its own within the galactic community, not one of an Artificial Intelligence becoming dispassionate and logical. And that doesn't even include the Morning War, which was not started by the AI attempting to wipe out its masters, but by the Quarian fear of what they Geth were and could do. The Geth are NOT an exploration of any concepts of the technological singularity.
EDI is another AI that basically comes to its own within the Mass Effect community. Granted I thought it was kind of a stretch to make EDI the AI you "defeated" at luna in Mass Effect 1, that also happened to give you an upgrade (Booh Yah!). But let's take that as a part of the story, since it was on a main quest. She starts out, like the Geth, as something that could have explored the Technological Singularity. In Mass Effect 1, she fights organics. However, in Mass Effect 2, she is a full fledged crew member. She has a sense of humor, and interacts and grows. Hell she's responsible for some of the funniest lines! "I like the sight of humans on their knees", "This is all Joker's fault. What a tool he was. I have to spend all day computing pi because he plugged in the Overlord.". Comon, you laughed. We all did. However, she wasn't fully unleashed until the end of Mass Effect 2, so she could still explore the technological singularity. But she didn't. Once unleashed she didn't because impassionate, logical, and indifferent. She became MORE human. MORE a part of the crew. A dispassionate AI wouldn't go to the collector base, wouldn't help them defeat them. Too much risk. In Mass Effect 3 EDI becomes basically human, and I don't mean she gets a body. I mean she makes decisions we all do. What's important to me, survival or my friends? Selfishness or Selflessness? Reguardless of her choices, the fact she is making them means she's becoming human. She can even start a relationship for goodness sake! She is another exploration of an AI becoming more and more human.
Notice a pattern here? The Geth and EDI both provide direct evidence that the real difference between synthetics and organics is actually pretty small. They are an exploration of awakening consciousness. Most importantly, they are NOT SCARY. They don't explore the technological singularity in any way. They don't state how AI outpaces organics, they don't show anything remotely like that. In fact, this exploration is completely contrary to the technological singularity. The Techonological Singularity requires that AI cannot coexist with organics. To explore AI that can for 99 hours, then say, whoops can't work is a conflicting theme that makes a bad ending.
The last AI explored are the Reapers themselves. Only they aren't. The motives of the Reapers are not explored until the last 10 minutes. And these people argue that the 14 lines of dialogue at the end completely put the Reapers as preventing the technological singularity? wait, scratch that, a lot of those lines are explaining what the "crucible could do", so its not even 14 lines. If you are telling me you can completely explain the motives of the Reapers in 7 lines or fewer of dialogue, then let me tell you that you are a moron. Also, it takes BALLS to argue that the Reapers are preventing the technological singularity, when they are literally the only AI in the story that could even be argued to explore the concept of the technological singularity at all! They could be argued to represent the eventuallity of that very concept!
Now, I do feel it necessary to address a point here. There are definately side quests that explore the Technological Singularity. The rogue citadel AI in Mass Effect 1, the loki mech saga in Mass Effect 2. However, these side quests don't affect the main plot, and can be completely skipped without any hinderance to the story. If the technological singularity was really an important concept to understand the Reapers, then it should NOT be skippable, and should be forced. If the writer's don't force you to care about it, IE it doesn't affect the main plot, then it is de facto evidence it isn't really important.
The problem here isn't that the technological singularity couldn't explain some of this, the problem is that the story doesn't explore that concept. You are literally telling the writer's of Mass Effect that it is okay to NOT tell you the story, that you will fill in the blanks that are missing to force it to make sence, and they call them geniuses for it. You are a sucker, and I don't care if you take offense to that or not. The narrative of the main plot of Mass Effect and missions that effect the main plot don't care about the Technological Singularity, and if you have to add external information into the narrative to force the motive of the main antagonist to make sense, that is a definition of narrative failure.
Let me also say this, it doesn't matter if the catalyst is a billion years old, and spent two hours recanting all the time's AI attacked organics. The point is NARRATIVE! The story doesn't explore those concepts. It doesn't matter if he *could* know everything, what matters is the story being told. The technological singularity does not belong as a part of the ending to Mass Effect. This is why the Extended Cut will suck. There needs to be complete thematic rewrite to the end to force it to make sense. Either that, or a complete rewrite of the other 99 hours of Mass Effect.
