A few interesting things.
From the briefing video, we have Alec Ryder, former N7, pathfinder. And next to him we have a description. Here:
I took notice on that last sentence (he did design SAM).
Alec became interested in artificial intelligence as a means of human advancement. 2 things right off the bat:
1, Bioware would have never written that if it were just meaningless fluff. It
totally is a foreshadowing of something.
2. I don't think I need to tell you that the whole brouhaha over the
entire last trilogy was
about AI in the first place.
So this is major, and it will definitely play a big role in the story.
His daughter has some affinities with Prothean artifacts and tech. Play with that how you will, I'm not terribly interested in that, but I can see how it
could play a major role (imagine if some protheans managed to escape to Andromeda 50k years before them....).
Take Cora Harper now:
Interesting tidbit: She is the second in command (next to Alec) and "if warranted his successor as Pathfinder". So how the heck do we become the next pathfinder? Interesting threads.
SAM is the AI desinged by Alec himself. Now, will SAM become a full fledged AI? The video describes how SAM is inherently linked with Alec himself. So an interesting possibility here is how Alec and SAM are probably going to try the full ME3
synthesis solution in one individual.
I'm probably overreaching here.
