The Architect says:
Your life is the sum of a remainder of an unbalanced equation inherent to the programming of the matrix. You are the eventuality of an anomaly, which despite my sincerest efforts I have been unable to eliminate from what is otherwise a harmony of mathematical precision. While it remains a burden to sedulously avoid it, it is not unexpected, and thus not beyond a measure of control. Which has led you, inexorably, here.
Questions:
Is the anomaly is the reason why someone in the matrix will eventually become the One?
How exactly is the anomaly applied to an individual in the matrix to become the One?
Was the anomaly embedded into Neo's RSI? Was it just waiting to be unlocked after he died (like when an update says you have to restart for it to take effect)?
I found this answer, but it doesn't fully answer what I'm asking.
