All People Are Machines
There is a lot of talk going around that Neo may infact be a machine. I don't necessarily agree with it but nor do I believe that it can not be. I see where people are coming from on this theory. He was made by machines as a form of control. But aren't all humans in this version of the Matrix some what machines. Not just the fact that they have plugs, but "humans are no longer born, they are grown." If machines grow humans then they would all be part machine, not just Neo alone.
