Of course, but that's merely a single example in a single civilization. BioWare isn't writing for one planet and one race, they're writing for an entire galaxy, and the galaxy isn't going to be filled with with friendly passive examples like yours. The life of organics is chaotic and unpredictable. Civilization A in one corner may create a benevolent A.I that's harmless, Civilization B in a different circumstance probably won't. Sooner or later those two will intersect and bad shit will happen.
Which is why I firmly believe you'd have to do some extremely impressive writing gymnastics to say that in Andromeda, a galaxy larger than the Milky Way and filled with intelligent life hasn't had at least one race fuck up and create a machine problem they couldn't fix, whether they have Mass Effect technology or not. You don't just magically overcome the problem of living beings creating other advanced beings to do the tasks they couldn't by escaping the story into another galaxy.
Arguably the majority of modern science fiction is based around or has featured an aspect of this issue. Terminator, Halo, Overwatch, System Shock, Star Wars, 2001: A Space Odyssey, Battlestar Galatica, Star Trek, etc etc. Trying to avoid it is not an option.
So yes, the topic is important, it is relevant, and I want BioWare to address it in-game, or at least in the Codexs.
