Erm, the salarians are shown to be looking into uplifting three different species in ME3. And genetic engineering was carefully regulated. Arguably as much as AI development (which still didn't prevent projects like Okeer's).
And not having to deal with organic uplifting in the ending just shows how foolish the ending was. Heck it proves being dependant on one type of technology blinds you to other paths. One of the enants of the game that was conveniently forgotten about in ME3
Yes, and they're looked down upon for doing so.
Here's the problem with the comparison between genetic uplifting and creation of artificial intelligence: the level of necessity behind the two technologies. Genetic advancing is another side of developments in medicine and physiology, which have been widely considered to be a necessity for the longevity of life. Creation of artificial intelligence, on the other hand, is derived directly from convenience, to handle remedial and/or dangerous jobs that could be done in other ways by organics.
And you, actually, are allowed to pave your own path in the ending, with the caveat that frying the Reapers will (logically) have repercussions. You have to build on the mistakes of this cycle to go forward.
A concern, yes. You don't see the difference between concerns that might have examples of danger and saying it's an all-out inevitability?
I see what's going on in our cultural and technological state in terms of artificial intelligence and don't discard it as a likely inevitability for this fictional universe, given the examples of it already occurring. And I don't see any problem with them working with the idea as an inevitability, or at least one perceived by the Catalyst's creators. Mass Effect's interpretation of a future might be out-of-date in forty or fifty years, of course, just like classic science-fiction movies and their outlook on where we'd be at this point.
Once again, concern, not fact. Whilst playing out the results of various speculations is part of science fiction stating that any of them are global, inevitable certainties is not. That's just plain crappy writing. It makes as much sense as saying "all aliens WILL want to eat us." Some may. Some sci-fi might have some aliens trying to do just that, and by having those it's giving individual examples, not claiming a universal truth. There is a massive difference.
No, it makes a lot more sense than the example you've presented, actually, given the evolution of synthetic intelligence over the past few decades. It's not "crappy writing", either; it's building off a feasible premise that we're already able to observe in rudimentary fashions. It also serves as its own form of cautionary tale, though this kind of cautionary tale is far from innovative.
Some might be. There's no reason to think that they are all like that and the game offers nothing to challenge that. Like I said, the huge, big important difference between "some" and "all". The capacity for that line of thinking existing is fine. Saying it is is inevitable is stupid.
It might not even be inevitable, once the Reapers are gone. That's up to the player to decide with their context.
