Bonesxte:
If you listen to what the Architect says to Neo then you would know he is not a machine.
"Although this process has altered your consciousness...you remain irrevocably human"
Then you get the info from the game FROM the Oracle:
"Neo has touched the source...he is trapped between our (the matrix) world and your world (the real world)."
There is no Matrix within a Matrix or 1 matrix with multiple levels etc. There is The Matrix and The Real world in which the Matrix resides along with the machines who created it. Zion is 100% real and it is all another level of control. The machines form of entertainment called "Slaughter the Humans" 🙂
I may actually sit down tonight and write an essay on the subject showing the points that Zion is in fact real etc and the points for the Matrix within a Matrix stuff. (if there is any).
