Ok, here's definitely something to think about. Because it's got my mind spinning.
Back in the first Matrix when Morpheus was showing Neo exactly what the Matrix was, you saw the fields of poeple who were being used for their electrical energy. You saw all of them in their own little capsule and plugged in. No interaction with one another. It's obvious that everyone dies at one point or another - whether their mind dies in the Matrix, or their body just gets too old in the real world.
Now how do they reproduce humans ??
If all the humans are separated in the real world, how can they possibly consummate (have some of that sex stuff) ?? Do they artificially inseminate women ?? If so, how do they go about getting the sperm from the man ??
