Glad to see some activity out here again!

I have a question maybe you guys can help me with. Every since I saw
Reloaded, something has bothered me.

In the scene with Neo and The Architect, The Architect says of one of
the programs, "If I am the father of the Matrix, she is its mother."
When Neo suggests that The Oracle is the program that The Architect is
referring to, The Architect scoffs saying, "Fhh-please."

If The Oracle isn't the mother, then who was The Architect referring to?
