In a long and boring meeting yesterday I finally worked out how Neo could affect and sense machine entities in the "real world" in Matrix Revolutions.
It makes sense that the machines are connected wirelessly, and it makes sense that they'd embed some sort of transmitter/receiver in the enslaved humans being used as "batteries" (as the spin would have us believe) or whatever, rather than just those big squirm-inducing sockets (quite literally the "fat pipe").
It could be something very low bandwidth included within the metalwork, but rather useful for when they need to locate individual units when disconnected. RFID rather than bluetooth, lets say. But still enough for Neo to master, and to use to his advantage. Lets face it, with enough effort and training you can engineer your central nervous system to enable it to perform all manner of previously-impossible things.
And you've got me thinking now, "train of thought", is that where top nineties TV comedy sketch show "Big Train" got its name (buy it HERE!)
And as for the neodymium magnet implants... NEOdymium... scary! It's all coming true...
Btw my Physicist mate Unit II used to work with incredibly powerful electromagnets running at near-absolute zero, and whenever I went near it my brain started glazing over. I used to be able to "feel" radioactivity at school as well. That means I'm either hypersensitive or hyper-psychosomatic. I reckon the latter.
