Satya's blog - Matrix Reloaded

Okay, here are my theories about neo stopping the sentinels outside the Matrix:
a) Implanted radio. He's got the hardware from being in the Matrix half his life, and now knows how to use it.
b) Matrix-within-the-matrix.
c) His signal was intercepted, he's still inside but in a containment sandbox.
Incidentally, I hope everyone noticed that a copy of Smith has cracked into and taken control of a human cortex.
