From what I understand, that Britannica Ball had all of the universe's known AI stored in it. Airiam got near it, the BB found out she could somehow store all the known AI information in the known universe within her immense SSD, and then she somehow transferred all of that information into the ship's computer. Without anyone else knowing. Until it became imperative to know something happened.
Next week I imagine they'll rewrite and stomp all over that idea telling us some other idea was behind it, and we should just forget what we've seen and heard to this point.
Damn, I can literally feel the IQ points being sucked out of my head when I watch this show.
