Final scene question
At the end of Revolutions the Architect tells the Oracle, she plaid a dangerous game (or something like that). She says that, well, every change is difficult.
What is the point of this dialogue? What are they talking about? Is the Archi. talking about the Oracle being taken over by Smith? But she couldn't prevent that, could she? Or, what else is he ltalking about? To what is he referring, and what did the Oracle had to do to make it less risky?
