the oracle said, rather, neo said and the oracle asserted, that the Source is the Machine Mainframe. I will not argue that all programs come from the Source. However, it is a Mainframe or server in that it controls everything that goes on. I do not see how the Source is pure energy. Where would you come up with this from? If it is pure energy, there must be something containing it. Also, how can it be pure energy if they get all their energy from the humans/batteries? Also, Neo would have to accelerate that Sentinel to the speed of light, or pour massive amounts of energy into that sentinel to convert it to energy. I don't see how he can do either from where he is at.
