Spoiler Warning for the entire series.
I think the robot could ultimately be behind the sabotage of the dynasty and it may be tied to the zero law, which if I am remembering correctly could allow her to end the dynasty so that it could save humanity from a larger whole of thirty thousand years of barbarism Harry predicted. The robots guiding humanity from afar despite the fact humanity abandoned and destroyed them as honored in the show. It would be a bizarre twist if she somehow was in fact the one somehow behind the destruction of the Star Bridge. A mystery that could have eight years worth of ramifications.
Religion is one of the ways that the Foundation uses to control society as it becomes a power within the periphery. For the more barbaric planets, could the idea of a sentient hologram assisting during crisis be a means of creating a pseudo religious following under the Foundation. Foundationism?
This is pure speculation on my part. I am not claiming to be correct. I am encouraging discussion and debate. Thank you. Namaste.
